The following are the changes in this release:
make clobber now removes the legacy files: have_fpos.h, help/man,
and help/usage. The latter 2 are now managed as help aliases
in help.c.
make install now removes the legacy files: ${HELPDIR}/man
and ${HELPDIR}/usage.
Fixed a problem where, when calc was linked with and uses GNU
readline then for any multi-line copy-and-paste, only the first
line is executed. Thanks to GitHub user @malfisya for reporting
this problem, and thanks to GitHub user @gromit1811 for doing
the research needed to overcome deficiencies in the GNU readline
documentation, and for supplying the work-a-round to allow
multi-line copy-and-paste to work as expected!
make clobber also removes the legacy files: help/man, and help/usage.
make install now removes the legacy files: ${HELPDIR}/man and
${HELPDIR}/usage.
Document the GNU readline then for any multi-line copy-and-paste
fix in CHANGES.
Fix for #138
According to
https://lists.gnu.org/archive/html/bug-readline/2024-01/msg00000.html
it's OK for readline() to return multi-line strings and/or newlines in case
of bracketed paste (enabled by default since readline 8.1) and also in other
situations even though its documentation explicitly states the opposite. So
we need to handle this properly in calc instead of just using the first line
and dropping the rest: Split the string returned by readline() into lines
and return line by line with each invocation of hist_getline(), each
possbily adding a terminating newline.
The following are the changes in this release:
Fixed bug that caused calc to fail to compile filepos2z() in file.c
on little endian machines for the Debian apcalc package. Thanks to
Martin Buck (m at rtin-buck dor de) for for fix.
Removed unused macros from zmath.h:
SWAP_B32_IN_HASH(dest, src)
SWAP_B16_IN_HASH(dest, src)
SWAP_B8_IN_HASH(dest, src)
SWAP_B32_IN_FLAG(dest, src)
SWAP_B16_IN_FLAG(dest, src)
SWAP_B8_IN_FLAG(dest, src)
When SWAP_HALF_IN_B32(dest, src), SWAP_B32_IN_FULL(dest, src),
SWAP_B16_IN_HALF(dest, src), SWAP_B32_IN_bool(dest, src),
or SWAP_B32_IN_LEN(dest, src), SWAP_HALF_IN_FILEPOS(dest, src)
is an assignment such as:
(*(dest) = *(src))
We now case the dest and src pointers to the proper type before
referencing and performing the assignment.
Documented unexpected behavior when calc is running in
"shell script mode" and the prompt builtin function is used
without the -p flag. Updated help/prompt, help/unexpected
and the calc man page accordingly.
Unless calc is given the -p command line option, calc will reopen
stdin as /dev/null instead of just closing stdin. This prevents
subsequent opens grabbing the 1st file descriptor.
Disable regress tests 4709, 4710, and 7763 because they print
multi-byte sequences, which are just fine for calc, the awk
used to evaluate the regression suite output in some legacy
systems report a "multibyte conversion failure".
Added a number of missing Makefile variables to the "make env" rule.
The man command is used to format the calc.1 man page into calc.usage.
The "help calc" command now prints the formatted calc man page (calc.usage).
The "help man" command now prints the formatted calc man page (calc.usage).
The "help usage" command now prints the formatted calc man page (calc.usage).
The file, calc.cat1, is formed by gzipping the calc.usage
formatted man page. The calc.cat1 is installed as the calc
cat section 1 man page.
Updated the Copyright string in version.c to refer to
the COPYING file and the "help copying" command.
Added calc.cat1 to .gitignore. Using "sort -d -u" to sort .gitignore content.
Avoiding use of modern [[ and ]] in Makefile for those legacy systems
whose shell do not support them. Be sure to use ||'s between []'s
to avoid problems with legacy shell such as the Bourne shell. *sigh*
Fixed the order of "help full" to match the order of topics listed
buy the "help help" command.
Sorted the halias[] help topics table in help.c using sort -d -u.
The top level Makefile needs to use multiple []'s between ||'s
to not cause problems for legacy shells such as the Bourne shell.
For example:
```make
-${Q} if [ -z "${MANDIR}" ] || [ ! -s calc.1 ]; then \
...
-${Q} if [ -z "${CATDIR}" ] || [ ! -s calc.cat1 ]; then \
```

The following are the changes in this release:
Updated BUGS about MSYS2 on Windows compiling of calc.
Added more git related checks and sanity checks to chk_tree.
Added ${FSANITIZE} make variable to Makefile.config to hold
common Address Sanitizer (ASAN) optins to modern Linux and macOS.
The Address Sanitizer is NOT enabled not compiled in by default.
Improved comments in Makefile.local for RHEL9.2 (Linux) and for
macOS 14.0 that, when uncommented and calc is recompiled (i.e.,
make clobber all) will enable the Address Sanitizer (ASAN) for calc.
Fixed memory leaks in the logn, aversin, acoversin, avercos,
acovercos, ahaversin, ahavercos, ahacovercos, aexsec,
aexcsc, and acrd.
Fixed a compile error in zmath.h that impacted legacy 32-bit Big
Endian machines. Thanks goes to GitHub user @gromit1811 for their
pull request.
Fixed the check for <sys/mount.h> when forming have_sys_mount.h.
Thanks goes to GitHub user @gromit1811 for their pull request.
Added "STATIC bool blum_initialized = false" to zrandom.c to improve
how the code detects if the Blum-Blum-Shub pseudo-random number
generator is seeded or not, and how to free the state correctly.
NOTE: There is a very minor memory leak in zrandom.c that will be
fixed in a later release.

generator is seeded or not, and how to free the state correctly.
NOTE: There is a very minor memory leak in zrandom.c that will be
fixed in a later release.
So far, the Makefile checked for sys/param.h instead and that suspiciously
looks like a copy & paste error.
Found by the Debian hurd-i386 build daemon because calc failed to compile
there and it seems to lack sys/mount.h. Not that this would be an extremely
relevant architecture these days, but nevertheless... ;-)
On ancient 32 bit big endian machines (e.g. MIPS) file.c fails to build
when FILEPOS is a struct and not a scalar. This happens because the
SWAP_HALF_IN_FILEPOS macro essentially expands to a simple assignment in
this case but the types are incompatile (HALF and FILEPOS).
Detailed compile error (this is from an older version so line numbers might
be wrong but the error is the same):
gcc -DCALC_SRC -DCUSTOM -Wall -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -O3 -g3 -Wno-error=long-long -Wno-long-long -c file.c
In file included from qmath.h:32,
from cmath.h:32,
from value.h:33,
from calc.h:33,
from file.c:39:
file.c: In function 'filepos2z':
zmath.h:85:46: error: incompatible types when assigning to type 'HALF' {aka 'long unsigned int'} from type 'FILEPOS' {aka 'struct _G_fpos_t'}
#define SWAP_HALF_IN_B32(dest, src) (*(dest) = *(src))
^
fposval.h:15:42: note: in expansion of macro 'SWAP_HALF_IN_B32'
#define SWAP_HALF_IN_FILEPOS(dest, src) SWAP_HALF_IN_B32(dest, src)
^~~~~~~~~~~~~~~~
file.c:1370:2: note: in expansion of macro 'SWAP_HALF_IN_FILEPOS'
SWAP_HALF_IN_FILEPOS(ret.v, &pos);
^~~~~~~~~~~~~~~~~~~~
Fix this by adding suitable casts to the definition of SWAP_HALF_IN_FILEPOS
on big endian machines. Strictly speaking, the casts only seem to be
necessary when using SWAP_HALF_IN_B32, but they can't hurt in the other
cases either.
The chk_tree will check for files in distlist that
would otherwise be ignored by trailblank or that
are used, by convention, as tempory / test files.
Fixed a shellcheck nit in trailblank.
Updated BUGS about MSYS2 on Windows compiling of calc.
Added more git related checks and sanity checks to chk_tree.
Added ${FSANITIZE} make variable to Makefile.config to hold
common Address Sanitizer (ASAN) optins to modern Linux and macOS.
The Address Sanitizer is NOT enabled not compiled in by default.
Improved comments in Makefile.local for RHEL9.2 (Linux) and for
macOS 14.0 that, when uncommented and calc is recompiled (i.e.,
make clobber all) will enable the Address Sanitizer (ASAN) for calc.
Before, make prep would show but not object to chk_tree failures.
Now, if all except chk_tree is OK, make prep will report:
almost satifactory except for chk_tree
The funclist.sed sed script, when transforming func.c
into help/funclist.c, was creating nested comments.
While those were hardless, a single change to func.c
avoids the naive funclist.sed processing and avoids
(harmless) warnings when compiling help/funclist.c
in the course of building the function list.
The following are the changes in this release:
The tarball for calc version 2.15.0.0 was missing version.h.
The version.h is now listed as part of the calc distribution.
Added the following new trigonometric functions:
versin(x [,eps]) versed trigonometric sine
coversin(x [,eps]) coversed trigonometric sine
vercos(x [,eps]) versed trigonometric cosine
covercos(x [,eps]) coversed trigonometric cosine
aversin(x [,eps]) inverse versed trigonometric sine
acoversin(x [,eps]) inverse coversed trigonometric sine
avercos(x [,eps]) inverse versed trigonometric cosine
acovercos(x [,eps]) inverse coversed trigonometric cosine
haversin(x [,eps]) half versed trigonometric sine
hacoversin(x [,eps]) half coversed trigonometric sine
havercos(x [,eps]) half versed trigonometric cosine
hacovercos(x [,eps]) half coversed trigonometric cosine
ahaversin(x [,eps]) inverse half versed trigonometric sine
ahacoversin(x [,eps]) inverse half coversed trigonometric sine
ahavercos(x [,eps]) inverse half versed trigonometric cosine
ahacovercos(x [,eps]) inverse half coversed trigonometric cosine
exsec(x [,eps]) exterior trigonometric secant
aexsec(x [,eps]) inverse exterior trigonometric secant
excsc(x [,eps]) exterior trigonometric cosecant
aexcsc(x [,eps]) inverse exterior trigonometric cosecant
crd(x [,eps]) trigonometric chord of a unit circle
acrd(x [,eps]) inverse trigonometric chord of a unit circle
cas(x [,eps]) trigonometric cosine plus sine
cis(x [,eps]) Euler's formula
As Msys2 is a fork of Cygwin, if the OSNAME is Msys, the Cygwin
target will be used. Thanks to GitHub user @iahung2 for the
pull request.
Support for win32 and DJGPP has been dropped. Calc version
2.14.3.5 was the last to make references to win32 and make
references to DJGPP. Future versions of calc may work under
those systems, we just elected to remove the somewhat out of
date and awkward `win32.mkdef` and related win32 references.
If you are a win32 user, please feel free to create a win32
target in Makefile.target and submit as a pull request.
If you are a DJGPP user, please feel free to create a DJGPP
target in Makefile.target and submit as a pull request.
Until someone can test such systems, we prefer to wait
until someone is able to test and supply a pull request.
Added PTR_LEN (length of a pointer) and PTR_BITS (bit length
of a pointer) to longbits.h.
Moved calc version definition from version.c to version.h.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
Fixed have_statfs optional executable file extension ${EXT{ in
the ${UTIL_PROGS} make variable.
Test if <stdint.h> exists and set HAVE_STDINT_H accordingly
in have_stdint.h. Added HAVE_STDINT_H to allow one to force
this value.
Test if <inttypes.h> exists and set HAVE_INTTYPES_H accordingly
in have_inttypes.h. Added HAVE_INTTYPES_H to allow one to force
this value.
Added c_chk.c to check the compiler and C include for calc
requirements. If you are unable to compile this program, or
if this program when compiles does not exit 0, then your C
compiler and/or C include fails to meet calc requirements.
Compilers that are at least c99 MUST be able to compile this
program such that when run will exit 0.
The "make hsrc" file will attempt to compile and run c_chk and
will warn if the C compiler and/or C include fails to meet
calc requirements. The "make debug" system will run c_chk -c
to print information about the C compiler and C include.
Currently failure to compile cc_chk.c or c_chk exiting non-0
will just print "WARNING!!" strings to stderr.
The make chk_c file also forms status.chk_c.h which either
defines CHK_C when the C compiler and select include files
appear to meet calc requirements, or undefines CHK_C
when it does not.
Added int.h as a central place for calc integer types and
integer macros.
Removed `-R release_file` and `-r release_file` command
line options from `ver_calc`. Add `-h` option. Updated
comments in "README.RELEASE", which serves as the contents
of the calc command "help release".
Added log2(x [,eps]) builtin function. When x is an integer
power of 2, log2(x) will return an integer, otherwise it will
return the equivalent of ln(x)/ln(2).
Removed CALC2_COMPAT in favor of ckecking if MAJOR_VER < 3.
The sign element in a ZVALUE is now of type SIGN, which is either
SB32 when MAJOR_VER < 3, or a bool otherwise.
The len element in a ZVALUE is of type LEN. LEN type is SB32 when
MAJOR_VER < 3, or a uintptr_t otherwise.
Setting an invalid epsilon via the epsilon(value) or confiv("epsilon",
value) triggers an error. The epsilon value must be: 0 < epsilon < 1.
Added new logn(x, n [,eps]) builtin to compute logarithms to base n.
Verify that eps arguments (error tolerance arguments that override
the default epsilon value) to builtin functions have proper values.
Previously the eps argument had little to no value checks for
many builtin functions.
Document in help files for builtin functions that take eps arguments,
the LIMIT range for such eps values.
Removed old Makefile testing rules for make dbx and make gdb.
Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.
Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release. Added the
update_ver tool, (formerly verupdate) and the trailblank tool
that existed outside of the calc source base but neverthless
used in the calc release process. Both of these tools are used
by "make prep".
Added Makefile testing rule "make testfuncsort" to check for
the sort of the builtin function list. Changed the order that
builtin functions are listed by "show builtin" and the help/builtin
to match the sorting of "LANG=C LC_ALL=C sort -d -u".
Added c_to_q(COMPLEX *c, bool cfree) to make is easier to convert
a COMPLEX value that is real (imag part is 0) into a NUMBER and
optionally free the COMPLEX value. The func.c code now uses c_to_q().
Added q_to_c(NUMBER *q) to make it easier to convert a NUMBER
into an allocated COMPLEX value.
Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.
Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.
Improved comments about use of the ${CALC_ENV} Makefile variable.
Noted in Makefile.cal where and how the ${CALC_ENV} is used.
Use ${CALC_ENV} Makefile variable were needed.
Modified regression test cal/regress.cal: in some cases test numbers
were adjusted. Add comments indicate which test numbers apply to
which code. Indicated where there is room for new tests.
Expanded the end of test numbers from 9999 to 99999.
To make the meaning a bit more clear in cal/regress.cal, we have
renamed the following test calc resource files that are related to
the calc regression test suite:
cal/test1700.cal -> cal/test8000.read.cal
cal/test2300.cal -> cal/test2300.obj_incdec.cal
cal/test2600.cal -> cal/test2600.numfunc.cal
cal/test2700.cal -> cal/test2700.isqrt.cal
cal/test3100.cal -> cal/test3100.matobj.cal
cal/test3400.cal -> cal/test3400.trig.cal
cal/test4000.cal -> cal/test4000.ptest.cal
cal/test4100.cal -> cal/test4100.redc.cal
cal/test4600.cal -> cal/test4600.fileop.cal
cal/test5100.cal -> cal/test5100.newdecl.cal
cal/test5200.cal -> cal/test5200.globstat.cal
cal/test8400.cal -> cal/test8400.quit.cal
cal/test8500.cal -> cal/test8500.divmod.cal
cal/test8600.cal -> cal/test8600.maxargs.cal
cal/set8700.cal -> cal/test8700.dotest.cal
cal/test8900.cal -> cal/test8900.special.cal
cal/test9300.cal -> cal/test9300.frem.cal
Added to test 94dd, read of a number of new calc resource files
that are not already read as a result of the calc regression test suite.
Fixed more documentation and code comments that referred to the
old additive 55 (a55) shuffle pseudo-random number generator.
We have been using the subtractive 100 shuffle pseudo-random
number generator in place of the additive 55 generator for a
while now.
Improved help files trigonometric functions. They were corrected
to indicate that complex arguments are allowed: an oversight
from long ago when those trigonometric functions were expanded
to include complex arguments. The EXAMPLE sections were expanded
and made consistent, where applicable, across the trigonometric
help files. Documented libcalc functions in the SEE ALSO sections.
Improved "SEE ALSO" for the hyperbolic function help files.
Expanded the calc regression test suite test 34dd to test various
real and complex values for trigonometric functions.
Added complex multiple approximation function to commath.c so
that users of libcalc may directly round complex number to
nearest multiple of a given real number:
E_FUNC COMPLEX *cmappr(COMPLEX *c, NUMBER *e, long rnd, bool cfree);
For example:
COMPLEX *c; /* complex number to round to nearest epsilon */
NUMBER *eps; /* epsilon rounding precision */
COMPLEX *res; /* c rounded to nearest epsilon */
long rnd = 24L; /* a common rounding mode */
bool ok_to_free; /* true ==> free c, false ==> do not free c */
...
res = cmappr(c, eps, ok_to_free);
The complex trigonometric functions tan, cot, sec, csc were
implemented in func.c as calls to complex sin and complex cos.
We added the following direct calls to comfunc.c so that users
of libcalc may call them directly:
E_FUNC COMPLEX *c_tan(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_sec(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
Added help/errorcodes rule to the top level Makefile.
Added E_USERMAX symbol (== 32767) to indicate the maximum value
allowed for user error codes.
Improved help/error. Added text about error code ranges and
range symbols.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Changed #define E_USERDEF to #define E__USERDEF.
Removed use of E_USERDEF, E__BASE, E__COUNT, and E__HIGHEST
from custom/c_sysinfo because the c_sysinfo is just a demo
and this will simplify the custom/Makefile.
The include file calcerr.h is now the errsym.h include file.
The calcerr.tbl has been replaced by errtbl.c and errtbl.h.
The calcerr_c.awk, calcerr_c.sed, calcerr_h.awk, and
calcerr_h.sed files are now obsolete and have been removed.
The calcerr.c and calcerr.h now obsolete and are no longer built.
The calc computation error codes, symbols and messages are now in
a error_table[] array of struct errtbl.
An E_STRING is a string corresponds to an error code #define.
For example, the E_STRING for the calc error E_STRCAT,
is the string "E_STRING". An E_STRING must now match
the regular expression: "^E_[A-Z0-9_]+$".
The old array error_table[] of error message strings has been
replaced by a new error_table[] array of struct errtbl. The struct
errtbl array holds calc errnum error codes, the related E_STRING
symbol as a string, and the original related error message.
To add new computation error codes, add them near the bottom of the
error_table[] array, just before the NULL entry.
The ./errcode utility, when run, will verify the consistency of
the error_table[] array.
The Makefile uses ./errcode -e to generate the contents of
help/errorcodes file. The help errorcodes now prints
information from the new cstruct errtbl error_table[] array.
The help/errorcodes.hdr and help/errorcodes.sed files are
now obsolete and have been removed.
The Makefile uses ./errcode -d to generate the contents of the
errsym.h include file.
Code that used the old array error_table[] of error message strings
such as:
#include "calcerr.h"
char *msg; /* calc computation error message */
msg = error_table[errnum - E__BASE];
where errnum is the calc computation error code
E__BASE <= errnum <= E__HIGHEST, may now use:
#include "errtbl.h"
#include "errsym.h"
char *msg; /* calc computation error message */
msg = error_table[errnum - E__BASE].errmsg;
Rename the #define E__COUNT to ECOUNT to avoid confusion
with "E_STRING" error symbols.
Renamed "E_1OVER0" to "E_DIVBYZERO".
Renamed "E_0OVER0" to "E_ZERODIVZERO".
The verify_error_table() function that does a verification
the error_table[] array and setup private_error_alias[] array
is now called by libcalc_call_me_first().
Fix comment about wrong include file in have_sys_mount.h.
Removed unused booltostr() and strtobool() macros from bool.h.
Moved define of math_error(char *, ...) from zmath.h to errtbl.h.
The errtbl.h include file, unless ERRCODE_SRC is defined
also includes attribute.h and errsym.h.
Added E_STRING to error([errnum | "E_STRING"]) builtin function.
Added E_STRING to errno([errnum | "E_STRING"]) builtin function.
Added E_STRING to strerror([errnum | "E_STRING"]) builtin function.
Calling these functions with an E_STRING errsym is the same as calling
them with the matching errnum code.
Standardized on calc computation error related E_STRING strings
where there are a set of related codes. Changed "E_...digits" into
"E_..._digits". For example, E_FPUTC1 became E_FPUTC_1, E_FPUTC2
became E_FPUTC_2, and E_FPUTC3 became E_FPUTC_3. In a few cases
such as E_APPR became E_APPR_1, because there was a E_APPR2 (which
became E_APPR_2) and E_APPR3 (which became E_APPR_3). To other
special cases, E_ILOG10 became E_IBASE10_LOG and E_ILOG2 became
E_IBASE2_LOG because E_ILOG10 and E_ILOG2 are both independent calc
computation error related E_STRING strings. Now related sets of
E_STRING strings end in _ (underscore) followed by digits.
Added errsym builtin function. The errsym(errnum | "E_STRING")
builtin, , when given a valid integer errnum that corresponds to a
calc error condition, will return an E_STRING string, AND when given
a valid E_STRING string that is associated with a calc error
condition, will return errnum integer that corresponds to a calc
error condition.
Supplying a non-integer numeric errnum code to error(), errno(),
strerror(), or errsym() will result in an error.
Added tests to the calc regression test suite (cal/regress.cal) to
verify that the errnum calc computation error codes and their
E_STRING values have not changed.
Improved the clarity of calc regression suite (regress.cal) to mostly
use E_STRING errsym instead of numeric errnum values for error()
and errno() related tests.
Fixed SEE ALSO typo in help randperm.
Fixed calc regression test 42dd to set the display value back to 20.
Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Added to test 34dd, some if the missing inverse trigonometric tests.
Improved builtin function strings, as printed by help builtin,
that use an optional accuracy (epsilon) arg by adding a comma.
The following are the changes from calc version 2.14.3.4 to 2.14.3.5:
Under macOS, to reduce dependency chains, we remove functions
and data that are unreachable by the entry point or exported
symbols. In particular, the macOS linker is used with both
"-dead_strip" and "-dead_strip_dylibs".
The libcalc shared library is now linked with libcustcalc.
The config("triground") controls rounding for the following
trigonometric and hyperbolic functions:
sin, cos, tan, cot, sec, csc
asin, acos, atan, acot, asec, acsc
versin, coversin, vercos, covercos
aversin, acoversin, avercos, acovercos
haversin, hacoversin, havercos, hacovercos
ahaversin, hacoversin, havercos, ahacovercos
exsec, aexsec, excsc, aexcsc
crd, acrd
cas, cis
sinh, cosh, tanh, coth, sech, csch
asinh, acosh, atanh, acoth, asech, acsch
In addition to taking a complex root (such as via the power
function on a complex value), "triground" is used for:
exp, polar
For the above mentioned functions, the rounding mode used to
round the result to the nearest epsilon value is controlled by,
and defaults to:
config("triground", 24)
As with other config options, the call returns the previous mode,
without a 2nd argument, returns the current mode without changing it:
config("triground")
When printing an error, calc used to print the errnum (error number):
; 1/0
Error 10001
Calc now prints the errsym (errsym):
; 1/0
Error E_DIVBYZERO
Added errsym E_LN_3 for ln(0).
Added errsym E_LOG_5 for log(0).
Added errsym E_LOG2_4 for log2(0).
Added errsym E_LOGN_6 for logn(0,base).
Added a chk_tree tool to help look for problems such as files that are
result of building calc that are also part of the calc distribution,
and files that are part of the calc source that are missing from the
calc distribution, and files that are of unknown status that are either
result of building calc nor missing from the calc distribution.
Updated file lists in Makefile, sorting as needed.
Updated Makefile PHONY rule to include Makefile rules that are NOT files.
Reduced make chatter for rules that build lists.
Added make verifydist to verify the existence of files that are part of
the calc distribution.
Added make verifydist to make prep.
Added a chk_tree double check, one after make clobber, one before
the final make chk, to make prep. Added double pass of chk_tree to
make full_debug (and thus to the make debug output).
Improved notes for install locations in Makefile.config.
Added printing of ${BUILD_ALL} to make env output.
Improved notes for install locations in Makefile.config.
Added printing of ${BUILD_ALL} to make env output.
Added double pass of chk_tree to make full_debug (and thus to the make
debug output).
The tarball for calc version 2.15.0.0 was missing version.h.
The version.h is now listed as part of the calc distribution.
Added a chk_tree tool to help look for problems such as files that are
result of building calc that are also part of the calc distribution,
and files that are part of the calc source that are missing from the
calc distribution, and files that are of unknown status that are either
result of building calc nor missing from the calc distribution.
Updated file lists in Makefile, sorting as needed.
Updated Makefile PHONY rule to include Makefile rules that are NOT files.
Reduced make chatter for rules that build lists.
Added make verifydist to verify the existence of files that are part of
the calc distribution.
Added make verifydist to make prep.
Added a chk_tree double check, one after make clobber, one before the
final make chk, to make prep.

As Msys2 is a fork of Cygwin, if the OSNAME is Msys, the Cygwin
target will be used. Thanks to GitHub user @iahung2 for the
pull request.
Support for win32 and DJGPP has been dropped. Calc version
2.14.3.5 was the last to make references to win32 and make
references to DJGPP. Future versions of calc may work under
those systems, we just elected to remove the somewhat out of
date and awkward `win32.mkdef` and related win32 references.
If you are a win32 user, please feel free to create a win32
target in Makefile.target and submit as a pull request.
If you are a DJGPP user, please feel free to create a DJGPP
target in Makefile.target and submit as a pull request.
Until someone can test such systems, we prefer to wait
until someone is able to test and supply a pull request.
Added PTR_LEN (length of a pointer) and PTR_BITS (bit length
of a pointer) to longbits.h.
Moved calc version definition from version.c to version.h.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
Fixed have_statfs optional executable file extension ${EXT{ in
the ${UTIL_PROGS} make variable.
Test if <stdint.h> exists and set HAVE_STDINT_H accordingly
in have_stdint.h. Added HAVE_STDINT_H to allow one to force
this value.
Test if <inttypes.h> exists and set HAVE_INTTYPES_H accordingly
in have_inttypes.h. Added HAVE_INTTYPES_H to allow one to force
this value.
Added c_chk.c to check the compiler and C include for calc
requirements. If you are unable to compile this program, or
if this program when compiles does not exit 0, then your C
compiler and/or C include fails to meet calc requirements.
Compilers that are at least c99 MUST be able to compile this
program such that when run will exit 0.
The "make hsrc" file will attempt to compile and run c_chk and
will warn if the C compiler and/or C include fails to meet
calc requirements. The "make debug" system will run c_chk -c
to print information about the C compiler and C include.
Currently failure to compile cc_chk.c or c_chk exiting non-0
will just print "WARNING!!" strings to stderr.
The make chk_c file also forms status.chk_c.h which either
defines CHK_C when the C compiler and select include files
appear to meet calc requirements, or undefines CHK_C
when it does not.
Added int.h as a central place for calc integer types and
integer macros.
Removed `-R release_file` and `-r release_file` command
line options from `ver_calc`. Add `-h` option. Updated
comments in "README.RELEASE", which serves as the contents
of the calc command "help release".
Added log2(x [,eps]) builtin function. When x is an integer
power of 2, log2(x) will return an integer, otherwise it will
return the equivalent of ln(x)/ln(2).
Removed CALC2_COMPAT in favor of ckecking if MAJOR_VER < 3.
The sign element in a ZVALUE is now of type SIGN, which is either
SB32 when MAJOR_VER < 3, or a bool otherwise.
The len element in a ZVALUE is of type LEN. LEN type is SB32 when
MAJOR_VER < 3, or a uintptr_t otherwise.
Setting an invalid epsilon via the epsilon(value) or confiv("epsilon",
value) triggers an error. The epsilon value must be: 0 < epsilon < 1.
Added new logn(x, n [,eps]) builtin to compute logarithms to base n.
Verify that eps arguments (error tolerance arguments that override
the default epsilon value) to builtin functions have proper values.
Previously the eps argument had little to no value checks for
many builtin functions.
Document in help files for builtin functions that take eps arguments,
the LIMIT range for such eps values.
Removed old Makefile testing rules for make dbx and make gdb.
Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.
Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release. Added the
update_ver tool, (formerly verupdate) and the trailblank tool
that existed outside of the calc source base but neverthless
used in the calc release process. Both of these tools are used
by "make prep".
Added Makefile testing rule "make testfuncsort" to check for
the sort of the builtin function list. Changed the order that
builtin functions are listed by "show builtin" and the help/builtin
to match the sorting of "LANG=C LC_ALL=C sort -d -u".
Added c_to_q(COMPLEX *c, bool cfree) to make is easier to convert
a COMPLEX value that is real (imag part is 0) into a NUMBER and
optionally free the COMPLEX value. The func.c code now uses c_to_q().
Added q_to_c(NUMBER *q) to make it easier to convert a NUMBER
into an allocated COMPLEX value.
Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.
Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.
Improved comments about use of the ${CALC_ENV} Makefile variable.
Noted in Makefile.cal where and how the ${CALC_ENV} is used.
Use ${CALC_ENV} Makefile variable were needed.
Modified regression test cal/regress.cal: in some cases test numbers
were adjusted. Add comments indicate which test numbers apply to
which code. Indicated where there is room for new tests.
Expanded the end of test numbers from 9999 to 99999.
To make the meaning a bit more clear in cal/regress.cal, we have
renamed the following test calc resource files that are related to
the calc regression test suite:
cal/test1700.cal -> cal/test8000.read.cal
cal/test2300.cal -> cal/test2300.obj_incdec.cal
cal/test2600.cal -> cal/test2600.numfunc.cal
cal/test2700.cal -> cal/test2700.isqrt.cal
cal/test3100.cal -> cal/test3100.matobj.cal
cal/test3400.cal -> cal/test3400.trig.cal
cal/test4000.cal -> cal/test4000.ptest.cal
cal/test4100.cal -> cal/test4100.redc.cal
cal/test4600.cal -> cal/test4600.fileop.cal
cal/test5100.cal -> cal/test5100.newdecl.cal
cal/test5200.cal -> cal/test5200.globstat.cal
cal/test8400.cal -> cal/test8400.quit.cal
cal/test8500.cal -> cal/test8500.divmod.cal
cal/test8600.cal -> cal/test8600.maxargs.cal
cal/set8700.cal -> cal/test8700.dotest.cal
cal/test8900.cal -> cal/test8900.special.cal
cal/test9300.cal -> cal/test9300.frem.cal
Added to test 94dd, read of a number of new calc resource files
that are not already read as a result of the calc regression test suite.
Fixed more documentation and code comments that referred to the
old additive 55 (a55) shuffle pseudo-random number generator.
We have been using the subtractive 100 shuffle pseudo-random
number generator in place of the additive 55 generator for a
while now.
Improved help files trigonometric functions. They were corrected
to indicate that complex arguments are allowed: an oversight
from long ago when those trigonometric functions were expanded
to include complex arguments. The EXAMPLE sections were expanded
and made consistent, where applicable, across the trigonometric
help files. Documented libcalc functions in the SEE ALSO sections.
Improved "SEE ALSO" for the hyperbolic function help files.
Expanded the calc regression test suite test 34dd to test various
real and complex values for trigonometric functions.
Added complex multiple approximation function to commath.c so
that users of libcalc may directly round complex number to
nearest multiple of a given real number:
E_FUNC COMPLEX *cmappr(COMPLEX *c, NUMBER *e, long rnd, bool cfree);
For example:
COMPLEX *c; /* complex number to round to nearest epsilon */
NUMBER *eps; /* epsilon rounding precision */
COMPLEX *res; /* c rounded to nearest epsilon */
long rnd = 24L; /* a common rounding mode */
bool ok_to_free; /* true ==> free c, false ==> do not free c */
...
res = cmappr(c, eps, ok_to_free);
The complex trigonometric functions tan, cot, sec, csc were
implemented in func.c as calls to complex sin and complex cos.
We added the following direct calls to comfunc.c so that users
of libcalc may call them directly:
E_FUNC COMPLEX *c_tan(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_sec(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
Added help/errorcodes rule to the top level Makefile.
Added E_USERMAX symbol (== 32767) to indicate the maximum value
allowed for user error codes.
Improved help/error. Added text about error code ranges and
range symbols.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Changed #define E_USERDEF to #define E__USERDEF.
Removed use of E_USERDEF, E__BASE, E__COUNT, and E__HIGHEST
from custom/c_sysinfo because the c_sysinfo is just a demo
and this will simplify the custom/Makefile.
The include file calcerr.h is now the errsym.h include file.
The calcerr.tbl has been replaced by errtbl.c and errtbl.h.
The calcerr_c.awk, calcerr_c.sed, calcerr_h.awk, and
calcerr_h.sed files are now obsolete and have been removed.
The calcerr.c and calcerr.h now obsolete and are no longer built.
The calc computation error codes, symbols and messages are now in
a error_table[] array of struct errtbl.
An E_STRING is a string corresponds to an error code #define.
For example, the E_STRING for the calc error E_STRCAT,
is the string "E_STRING". An E_STRING must now match
the regular expression: "^E_[A-Z0-9_]+$".
The old array error_table[] of error message strings has been
replaced by a new error_table[] array of struct errtbl. The struct
errtbl array holds calc errnum error codes, the related E_STRING
symbol as a string, and the original related error message.
To add new computation error codes, add them near the bottom of the
error_table[] array, just before the NULL entry.
The ./errcode utility, when run, will verify the consistency of
the error_table[] array.
The Makefile uses ./errcode -e to generate the contents of
help/errorcodes file. The help errorcodes now prints
information from the new cstruct errtbl error_table[] array.
The help/errorcodes.hdr and help/errorcodes.sed files are
now obsolete and have been removed.
The Makefile uses ./errcode -d to generate the contents of the
errsym.h include file.
Code that used the old array error_table[] of error message strings
such as:
#include "calcerr.h"
char *msg; /* calc computation error message */
msg = error_table[errnum - E__BASE];
where errnum is the calc computation error code
E__BASE <= errnum <= E__HIGHEST, may now use:
#include "errtbl.h"
#include "errsym.h"
char *msg; /* calc computation error message */
msg = error_table[errnum - E__BASE].errmsg;
Rename the #define E__COUNT to ECOUNT to avoid confusion
with "E_STRING" error symbols.
Renamed "E_1OVER0" to "E_DIVBYZERO".
Renamed "E_0OVER0" to "E_ZERODIVZERO".
The verify_error_table() function that does a verification
the error_table[] array and setup private_error_alias[] array
is now called by libcalc_call_me_first().
Fix comment about wrong include file in have_sys_mount.h.
Removed unused booltostr() and strtobool() macros from bool.h.
Moved define of math_error(char *, ...) from zmath.h to errtbl.h.
The errtbl.h include file, unless ERRCODE_SRC is defined
also includes attribute.h and errsym.h.
Added E_STRING to error([errnum | "E_STRING"]) builtin function.
Added E_STRING to errno([errnum | "E_STRING"]) builtin function.
Added E_STRING to strerror([errnum | "E_STRING"]) builtin function.
Calling these functions with an E_STRING errsym is the same as calling
them with the matching errnum code.
Standardized on calc computation error related E_STRING strings
where there are a set of related codes. Changed "E_...digits" into
"E_..._digits". For example, E_FPUTC1 became E_FPUTC_1, E_FPUTC2
became E_FPUTC_2, and E_FPUTC3 became E_FPUTC_3. In a few cases
such as E_APPR became E_APPR_1, because there was a E_APPR2 (which
became E_APPR_2) and E_APPR3 (which became E_APPR_3). To other
special cases, E_ILOG10 became E_IBASE10_LOG and E_ILOG2 became
E_IBASE2_LOG because E_ILOG10 and E_ILOG2 are both independent calc
computation error related E_STRING strings. Now related sets of
E_STRING strings end in _ (underscore) followed by digits.
Added errsym builtin function. The errsym(errnum | "E_STRING")
builtin, , when given a valid integer errnum that corresponds to a
calc error condition, will return an E_STRING string, AND when given
a valid E_STRING string that is associated with a calc error
condition, will return errnum integer that corresponds to a calc
error condition.
Supplying a non-integer numeric errnum code to error(), errno(),
strerror(), or errsym() will result in an error.
Added tests to the calc regression test suite (cal/regress.cal) to
verify that the errnum calc computation error codes and their
E_STRING values have not changed.
Improved the clarity of calc regression suite (regress.cal) to mostly
use E_STRING errsym instead of numeric errnum values for error()
and errno() related tests.
Fixed SEE ALSO typo in help randperm.
Fixed calc regression test 42dd to set the display value back to 20.
Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Added to test 34dd, some if the missing inverse trigonometric tests.
Improved builtin function strings, as printed by help builtin,
that use an optional accuracy (epsilon) arg by adding a comma.
When printing an error, calc used to print the errnum (error number):
; 1/0
Error 10001
Calc now prints the errsym (errsym):
; 1/0
Error E_DIVBYZERO
Added errsym E_LN_3 for ln(0).
Added errsym E_LOG_5 for log(0).
Added errsym E_LOG2_4 for log2(0).
Added errsym E_LOGN_6 for logn(0,base).
The config("triground") controls rounding for the following
trigonometric and hyperbolic functions:
sin, cos, tan, cot, sec, csc
asin, acos, atan, acot, asec, acsc
versin, coversin, vercos, covercos
aversin, acoversin, avercos, acovercos
haversin, hacoversin, havercos, hacovercos
ahaversin, hacoversin, havercos, ahacovercos
exsec, aexsec, excsc, aexcsc
crd, acrd
cas, cis
sinh, cosh, tanh, coth, sech, csch
asinh, acosh, atanh, acoth, asech, acsch
In addition to taking a complex root (such as via the power
function on a complex value), "triground" is used for:
exp, polar
For the above mentioned functions, the rounding mode used to
round the result to the nearest epsilon value is controlled by,
and defaults to:
config("triground", 24)
As with other config options, the call returns the previous mode,
without a 2nd argument, returns the current mode without changing it:
config("triground")
Improved "SEE ALSO" for the hyperbolic function help files.
Improve builtin function strings, as printed by help builtin,
that use an optional accuracy (epsilon) arg by adding a comma.
Added the following new trigonometric functions:
crd(x [,eps]) trigonometric chord of a unit circle
acrd(x [,eps]) inverse trigonometric chord of a unit circle
Added the following new trigonometric functions:
exsec(x [,eps]) exterior trigonometric secant
aexsec(x [,eps]) inverse exterior trigonometric secant
excsc(x [,eps]) exterior trigonometric cosecant
aexcsc(x [,eps]) inverse exterior trigonometric cosecant
Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Added to test 34dd, some if the missing inverse trigonometric tests.
Fixed SEE ALSO typo in help randperm.
Added the following new trigonometric functions:

hacovercos(x [,eps]) half coversed trigonometric cosine
ahaversin(x [,eps]) inverse half versed trigonometric sine
ahacoversin(x [,eps]) inverse half coversed trigonometric sine
ahavercos(x [,eps]) inverse half versed trigonometric cosine
ahacovercos(x [,eps]) inverse half coversed trigonometric cosine
Fixed calc regression test 42dd to set the display value back to 20.
Added test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Fix and improve recently comments and variable names added new
trigonometric functions in comfunc.c, func.c, qtrans.c.
The trigonometric file files have had several bug fixed.
The EXAMPLE sections of trigonometric file have
been made consistent.
Added these new help files in anticipation of
the code for these new (i.e., to be written) builtin functions:
hacovercos hacoversin havercos haversin
ahacovercos ahacoversin ahavercos ahaversin
Rename E_BROUND to E_BROUND_1 as per an earlier change
on the E_STRING formats.
E_BROUND ==> E_BROUND_1
Improve the ciarify of calc regression suite (regress.cal) to mostly
use E_STRING errsym instead of numeric errnum values for error()
and errno() related tests.
Added tests to the calc regression test suite (cal/regress.cal) to
verify that the errnum calc computation error codes and their
E_STRING values have not changed.
NOTE: errstr was renamed to errsym.
Added errsym builtin function. The errsym(errnum | "E_STRING")
builtin, , when given a valid integer errnum that corresponds to a
calc error condition, will return an E_STRING string, AND when given
a valid E_STRING string that is associated with a calc error
condition, will return errnum integer that corresponds to a calc
error condition.
Supplying a non-integer numeric errnum code to error(), errno(),
strerror(), or errsym() will result in an error.
When errtbl.c is being compiled for the errcode executable,
(when ERRCODE_SRC is defined), skip functions that make
called to math_error() and name_newerrorstr() from libcalc.
Now the "E_STRING" errsym strings in error_table[], with exception
to the 1st E__BASE entry, all other errsym strings must match the
following regular expression:
^E_[A-Z][A-Z0-9_]+$
Renamed "E_1OVER0" to "E_DIVBYZERO".
Renamed "E_0OVER0" to "E_ZERODIVZERO".
Removed from errsym.h (as built by errcode -d via the Makefile),
E__NONE, E__BASE, E__USERDEF, and E__USERMAX. These symbols were
also defined in errtbl.h, which is NOW the place of the #define.
Update .gitigore with another temporary file.
Rename the #define E__COUNT to ECOUNT to avoid confusion
with "E_STRING" error symbols.
Improve formatting of help/error, help/errno, and help/strerror.
Update .gitignore.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Changed #define E_USERDEF to #define E__USERDEF.
Removed use of E_USERDEF, E__BASE, E__COUNT, and E__HIGHEST
from custom/c_sysinfo because the c_sysinfo is just a demo
and this will simplify the custom/Makefile.
The include file calcerr.h is now the errsym.h include file.
The calcerr.tbl has been replaced by errtbl.c and errtbl.h.
The calcerr_c.awk, calcerr_c.sed, calcerr_h.awk, and
calcerr_h.sed files are now obsolete and have been removed.
The calcerr.c and calcerr.h now obsolete and are no longer built.
The calc computation error codes, symbols and messages are now in
a error_table[] array of struct errtbl.
An E_STRING is a string corresponds to an error code #define.
For example, the E_STRING for the calc error E_STRCAT,
is the string "E_STRING". An E_STRING must now match
the regular expression: "^E_[A-Z0-9_]+$".
The old array error_table[] of error message strings has been
replaced by a new error_table[] array of struct errtbl. The struct
errtbl array holds calc errnum error codes, the related E_STRING
symbol as a string, and the original related error message.
To add new computation error codes, add them near the bottom of the

The help/errorcodes.hdr and help/errorcodes.sed files are
now obsolete and have been removed.
The Makefile uses ./errcode -d to generate the contents of the
errsym.h include file.
Updated .gitignore and trailblank to support the above changes.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Added help/errorcodes rule to the top level Makefile.
Added E_USERMAX symbol (== 32767) to indicate the maximum value
allowed for user error codes.
Improve help/error. Added text about error code ranges and
range symbols.
Added complex multiple approximation function to commath.c so
that users of libcalc may directly round complex number to
nearest multiple of a given real number:
E_FUNC COMPLEX *cmappr(COMPLEX *c, NUMBER *e, long rnd, bool cfree);
For example:
COMPLEX *c; /* complex number to round to nearest epsilon */
NUMBER *eps; /* epsilon rounding precision */
COMPLEX *res; /* c rounded to nearest epsilon */
long rnd = 24L; /* a common rounding mode */
bool ok_to_free; /* true ==> free c, false ==> do not free c */
...
res = cmappr(c, eps, ok_to_free);
The complex trigonometric functions tan, cot, sec, csc were implemented
in func.c as calls to complex sin and complex cos. We added the
direct calls to comfunc.c so that users of libcalc may
call them directly:
E_FUNC COMPLEX *c_tan(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_sec(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
Improved help files for sin, cos, tan, cot, sec, csc. In case
of tan, cot, sec, csc corrected help file was corrected to
indicate that complex arguments are allowed. This was a help
file oversight from long ago when those trigonometric functions
Expanded the calc regression test suite test 34dd to test various
real and complex values for sin, cos, tan, cot, sec, csc.
Fixed more documentation and code comments that referred to the old
additive 55 (a55) shuffle pseudo-random number generator. We have
been using the subtractive 100 shuffle pseudo-random number generator
in place of the additive 55 generator for a while now.
Updated the cal/README to reflect the new names
of the calc regression test suite files.
Updated cal/Makefile to remove, when installing,
old names for calc regression test suite files.
Added missing getpgid_tmp to .gitignore.
To make the meaning a bit more clear in cal/regress.cal, we have
renamed the following test calc resource files that are related to
the calc regression test suite:
cal/test1700.cal -> cal/test8000.read.cal
cal/test2300.cal -> cal/test2300.obj_incdec.cal
cal/test2600.cal -> cal/test2600.numfunc.cal
cal/test2700.cal -> cal/test2700.isqrt.cal
cal/test3100.cal -> cal/test3100.matobj.cal
cal/test3400.cal -> cal/test3400.trig.cal
cal/test4000.cal -> cal/test4000.ptest.cal
cal/test4100.cal -> cal/test4100.redc.cal
cal/test4600.cal -> cal/test4600.fileop.cal
cal/test5100.cal -> cal/test5100.newdecl.cal
cal/test5200.cal -> cal/test5200.globstat.cal
cal/test8400.cal -> cal/test8400.quit.cal
cal/test8500.cal -> cal/test8500.divmod.cal
cal/test8600.cal -> cal/test8600.maxargs.cal
cal/set8700.cal -> cal/test8700.dotest.cal
cal/test8900.cal -> cal/test8900.special.cal
cal/test9300.cal -> cal/test9300.frem.cal
Added to test 94dd, read of a number of new calc resource files
that are not already read as a result of the calc regression test suite.
Improve comments about use of the ${CALC_ENV} Makefile variable.
Noted in Makefile.cal where and how the ${CALC_ENV} is used.
Use ${CALC_ENV} Makefile variable were needed.
Modified regression test cal/regress.cal: in some cases test numbers
were adjusted. Add comments indicate which test numbers apply to
which code. Indicated where there is room for new tests.
Expanded the end of test numbers from 9999 to 99999.
Fixed how the historical trigonometric functions call
the underlying trigonometric functions. This fixes a
number of issues where the function for values of 0.
Updated cal/regress.cal to test historical trigonometric functions
at the 0 value.
Improved trig help files.
Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.
Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.
In cases where the real value to the inverse versed sine and the
inverse coversed sine function produces a complex value, the
conversion from real to complex was incorrect.
Added c_to_q(COMPLEX *c, bool cfree) to make is easier to convert
a COMPLEX value that is real (imag part is 0) into a NUMBER and
optionally free the COMPLEX value.
The func.c code now uses c_to_q().
NOTE: There is a XXX bug marked in the f_aversin() and f_acoversin()
that still needs to be fixed.
Added new aversin(x, [,eps]) for inverse versed sine and acoversin(x, [,eps])
for inverse coversed sine.
Improved trig function help files to reference use of complex arguments
that while supported were not documented.
Removed old Makefile testing rules for make dbx and make gdb.
Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.
Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release.
Added Makefile testing rule testfuncsort to check for the sort
of the builtin function list. Changed the order that builtin
functions are listed by "show builtin" and the help/builtin to
match the sorting of "LANG=C LC_ALL=C sort -d -u".
Moved versin() and coversin() to bottom of functions in func.c
(however the builtin function list remains sorted).
Created a historical trig functions section for cmath.h and qmath.h.
Moved cal/test3500.cal to cal/test9300.cal to make room
for future trip tests going from test 3427 thru 3599.
Add new logn(x, n [,eps]) builtin to compute logarithms to base n.
Verify that eps arguments (error tolerance arguments that override
the default epsilon value) to builtin functions have proper values.
Previously the eps argument had little to no value checks for
many builtin functions.
Document in help files for builtin functions that take eps arguments,
the LIMIT range for such eps values.
Removed CALC2_COMPAT in favor of ckecking if MAJOR_VER < 3.
The sign element in a ZVALUE is now of type SIGN, which is either
SB32 when MAJOR_VER < 3, or a bool otherwise.
The len element in a ZVALUE is of type LEN. LEN type is SB32 when
MAJOR_VER < 3, or a uintptr_t otherwise.
Noted version.h symbols in README.RELEASE instead of CALC2_COMPAT.
Improve .gitignore. Add excludes of hsrc temporary and test
programs. Added note about how the list is sorted.
Moved the generic excludes to the top.
Change zispowerof2() interaface to take a FULL ptr as the 2nd arg:
zispowerof2(ZVALUE z, FULL *log2).
Added qispowerof2(NUMBER *q, NUMBER **qlog2) to qfunc.c.
Change log2() builtin to use the new qispowerof2() internal interface.
Update LIBRARY to reflect the new zispowerof2() internal interface
and the new qispowerof2() internal interface.
Added log2(x [,eps]) builtin function. When x is an integer
power of 2, log2(x) will return an integer, otherwise it will
return the equivalent of ln(x)/ln(2).
Removed `-R release_file` and `-r release_file` command
line options from `ver_calc`. Add `-h` option. Updated
comments in "README.RELEASE", which serves as the contents
of the calc command "help release".
The z*.c functions that take pointers that cannot be NULL are checked
for NULL pointers at the beginning of the function.
While calc is not known to pass bogus NULL pointers to ZVALUE related
code, libcalc could be called by external code that might do so by
mistake. If that happens, math_error() is called with the name of
the function and the name of the arg that was NULL.
The int.h will trigger an error when CHK_C is undefined and MAJOR_VER
>= 3. Improved the int.h error message in this case.
Added some comments and C integers to int.h.
Added int.h as a centeral place for calc integer types and integer macros.
Currently zmath.c includes int.h but does not yet use it.
Added missing ptr type checks to chk_c.c.
The make chk_c file also forms status.chk_c.h which either
defines CHK_C when the C compiler and select include files
appear to meet calc requirements, or undefines CHK_C
when it does not.
Fixed have_statfs optional executable file extension ${EXT{ in
the ${UTIL_PROGS} make variable.
Prevented the "fake boolean value" when <stdbool.h> is missing,
from complicating C compilers post c17 standard.
Test if <stdint.h> exists and set HAVE_STDINT_H accordingly
in have_stdint.h. Added HAVE_STDINT_H to allow one to force
this value.
Test if <inttypes.h> exists and set HAVE_INTTYPES_H accordingly
in have_inttypes.h. Added HAVE_INTTYPES_H to allow one to force
this value.
Added c_chk.c to check the compiler and C include for calc
requirements. If you are unable to compile this program, or
if this program when compiles does not exit 0, then your C
compiler and/or C include fails to meet calc requirements.
Compilers that are at least c99 MUST be able to compile this
program such that when run will exit 0.
The "make hsrc" file will attempt to compile and run c_chk and
will warn if the C compiler and/or C include fails to meet
calc requirements. The "make debug" system will run c_chk -c
to print information about the C compiler and C include.
Currently failure to compile cc_chk.c or c_chk exiting non-0
will just print "WARNING!!" strings to stderr.
Fix "Under source code control" date for new version.h file.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
The sign in a ZVALUE is now of type SIGN, whcih is either
SB32 when CALC2_COMPAT is defined, or a bool.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
Moved calc version definition from version.c to version.h.
Added CALC2_COMPAT, that when defined attempts to maintain calc
version 2 compatibility. When MAJOR_VER <= 2, CALC2_COMPAT is
defined. This is anticipation for a future calc version 3 code.
Support for win32 and DJGPP has been dropped. Calc version
2.14.3.5 was the last to make references to win32 and make
references to DJGPP. Future versions of calc may work under
those systems, we just elected to remove the somewhat out of
date and awkward `win32.mkdef` and related win32 references.
If you are a win32 user, please feel free to create a win32
target in Makefile.target and submit as a pull request.
If you are a DJGPP user, please feel free to create a DJGPP
target in Makefile.target and submit as a pull request.
Until someone can test such systems, we prefer to wait
until someone is able to test and supply a pull request.
The following are the changes in this release:
Under macOS, to reduce dependency chains, we remove functions
and data that are unreachable by the entry point or exported
symbols. In particular, the macOS linker is used with both
"-dead_strip" and "-dead_strip_dylibs".
The libcalc shared library is now linked with libcustcalc.

Fixed rpm spec file.
The following are the changes in this release:
Fix typo in the `make debug` Makefile rule.
Improved .gitignore to ignore .static, calc-static,
sample_many-static and sample_rand-static.
Improved error messages when trying to compile with
with one calc type (when BLD_TYPE=calc-dynamic-only or
BLD_TYPE=calc-static-only) and install with the other.
When installing with BLD_TYPE=calc-static-only, the
installed calc and calc-static are links to each other.
Thanks to GitHub user @TurtleWilly for this suggestion.
The dynamic shared libraries are not installed if they are not
built. So when installing with BLD_TYPE=calc-static-only, the
install rule will not attempt to install dynamic shared libraries.
Thanks to GitHub user @TurtleWilly for bringing to our attention,
problems related to building a statically linked calc under macOS.
Updated comments in Makefile.local for how to Diagnosing memory,
thread, and crash issues under RHEL and macOS.
We no longer support the Makefile variable ${ALLOW_CUSTOM} to be empty.
Normally ${ALLOW_CUSTOM} is:
ALLOW_CUSTOM= -DCUSTOM
Now, to disable custom disable custom even if -C is given, use:
ALLOW_CUSTOM="-UCUSTOM"
Dropped support of Makefile.simple and custom/Makefile.simple.
The calc version 2.14.3.0 is the last release that supported
the Makefile.simple and custom/Makefile.simple files.
Now, a make that supports makefile conditional syntax is required.
The simple target, a target that only was used for Makefile.simple
was removed.
Moved makefile variables that configure calc and configure how to
compile calc from Makefile into a new Makefile.config file.
The Makeifle includes the Makefile.config file.
The cal/Makeifle includes the Makefile.config file.
The cscript/Makeifle includes the Makefile.config file.
The custom/Makeifle includes the Makefile.config file.
The help/Makeifle includes the Makefile.config file.
Now, the Makefile.config file will consistently configure
calc and how calc is compiled and built by all calc Makefiles.
The custom/Makefile no longer includes Makefile.
The platform target section from the old Makefile has been moved
to a new file, Makefile.target. Improved the format and comments
in target information.
The Makeifle includes the Makefile.target file.
The cal/Makeifle includes the Makefile.target file.
The cscript/Makeifle includes the Makefile.target file.
The custom/Makeifle includes the Makefile.target file.

The cal/Makeifle includes the Makefile.local file.
The cscript/Makeifle includes the Makefile.local file.
The custom/Makeifle includes the Makefile.local file.
The help/Makeifle includes the Makefile.local file.
Thus, one may modify or append many Makefile variables
in all calc Makefiles.
Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.
Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM). The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable. However when CUSTOM
is undefined, the bulk of custom functions are not defined.
Dropped the use of Makefile variable ${SET_INSTALL_NAME}.
Under macOS it was always needed, elsewhere it was not.
Added Makefile variable ${VER} to hold the calc major release version.
The calc major release version is a 3 level version (x.y.z).
Under macOS, the current version of both libcalc and libcustcalc
shared libraries are set to the current calc major release version.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the macOS linker is used with "-dead_strip" by default.
While calc on macOS will execute if linker used with "-dead_strip_dylibs"
and CUSTOM is defined, other applications that use libcalc but not
libcustcalc (such as sample_many and sample_rand) will fail to execute
due to missile symbols. Therefore "-dead_strip_dylibs" is not used
by default when ALLOW_CUSTOM is "-DCUSTOM" under macOS.
Thanks to GitHub user @TurtleWilly for bringing to our attention,
problems related to use of "-dead_strip_dylibs".
When installing shared libraries, libcalc.x.y.z will be a link
to the libcalc shared library and libcustcalc.x.y.z will be a link

to the libcalc shared library and libcustcalc.x.y.z will be a link
to the libcustcal shared library.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the macOS linker is used with "-dead_strip" by default.
While calc on macOS will execute if linker used with "-dead_strip_dylibs"
and CUSTOM is defined, other applications that use libcalc but not
libcustcalc (such as sample_many and sample_rand) will fail to execute
due to missile symbols. Therefore "-dead_strip_dylibs" is not used
by default when ALLOW_CUSTOM is "-DCUSTOM" under macOS.

Added Makefile variable ${VER} to holdthe calc major release version.
The calc major release version is a 3 level version (x.y.z).
Under macOS, the current version of both libcalc and
libcustcalc are set to the current calc major release version.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip" and with
"-dead_strip_dylibs".
The macOS ld documentation states that option should not be used
when linking against a dylib which is required at runtime for some
indirect reason such as the dylib has an important initializer.
The libcustcalc appears to have such an initializer.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip" and with
"-dead_strip_dylibs".
Dropped the use of Makefile variable ${SET_INSTALL_NAME}.
Under macOS it was always needed, elsewhere it was not.

libcustcalc are set to the current calc release version.
Under macOS, to reduce dependency chains, we remove functions and

In particular, the linker is run with "-dead_strip".
Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.
Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM). The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable. However when CUSTOM
is undefined, the bulk of custom functions are not defined.
Moved makefile variables that configure calc and configure how to
compile calc from Makefile into a new Makefile.config file.
The Makeifle includes the Makefile.config file.
The cal/Makeifle includes the Makefile.config file.
The cscript/Makeifle includes the Makefile.config file.
The custom/Makeifle includes the Makefile.config file.
The help/Makeifle includes the Makefile.config file.
Now, the Makefile.config file will consistently configure
calc and how calc is compiled and built by all calc Makefiles.
The platform target section from the old Makefile has been moved to
a new file, Makefile.target. The custom/Makefile no longer includes
Makefile.
The Makeifle includes the Makefile.target file.
The cal/Makeifle includes the Makefile.target file.
The cscript/Makeifle includes the Makefile.target file.
The custom/Makeifle includes the Makefile.target file.
The help/Makeifle includes the Makefile.target file.
Now, the Makefile.target file will consistently set
target information for all calc Makefiles.
The cal/Makeifle includes the Makefile.local file.
The cscript/Makeifle includes the Makefile.local file.
The custom/Makeifle includes the Makefile.local file.
The help/Makeifle includes the Makefile.local file.
Thus, one may modify or append many Makefile variables
in all calc Makefiles.
Dropped support of Makefile.simple and custom/Makefile.simple.
The calc version 2.14.3.0 is the last release that supported
the Makefile.simple and custom/Makefile.simple files.
Now, a make that supports makefile conditional syntax is required.
The platform target section from the old Makefile has been moved
to a new file, Makefile.target. The Makefile.target is shared
by both Makefile and custom/Makefile. The custom/Makefile no
longer includes Makefile (instead it includes ../Makefile.target).
Updated comments in Makefile.local for how to Diagnosing memory,
thread, and crash issues under RHEL and macOS.
We no longer support the Makefile variable ${ALLOW_CUSTOM} to be empty.
Normally ${ALLOW_CUSTOM} is:
ALLOW_CUSTOM= -DCUSTOM
Now, to disable custom disable custom even if -C is given, use:
ALLOW_CUSTOM="-UCUSTOM"
Added comments in Makefile.local for how to reduce dependency chains
under macOS. XXX - this doesn't yet work so don't uncomment - XXX.
Improved .gitignore to ignore .static, calc-static,
sample_many-static and sample_rand-static.
Improved error messages when trying to compile with
with one calc type (when BLD_TYPE=calc-dynamic-only or
BLD_TYPE=calc-static-only) and install with the other.
When installing with BLD_TYPE=calc-static-only, the
installed calc and calc-static are links to each other.
Thanks to GitHub user @urtleWilly for this suggestion.
The dynamic shared libraries are not installed if they are not
built. So when installing with BLD_TYPE=calc-static-only, the
install rule will not attempt to install dynamic shared libraries.
Thanks to GitHub user @urtleWilly for bringing to our attention,
problems related to building a statically linked calc under macOS.
The following are the changes in this release:
Updated COPYING to include the actual text of "The Unlicense".
Made minor formatting changes to the file.
The Darwin specific ${DARWIN_ARCH}, thay by default was unset,
is now the ${ARCH_CFLAGS} Makefile variable. Comments about
various "-arch name" have been moved to the ${ARCH_CFLAGS} area.
For old Apple Power PC systems, the following is added:
COMMON_CFLAGS+= -std=gnu99
COMMON_LDFLAGS+= -std=gnu99
ARCH_CFLAGS+= -arch ppc
Old Apple Power PC systems should be detected by the
"uname -p" command returning "powerpc". One may force the
Power PC mode by adding to the end of any make command:
make ...make_args... target=Darwin arch=powerpc
or by adding the following in the Makefile.local file:
target= Darwin
arch= powerpc
Improved the output of the calcinfo rule by adding echos
of various uname values as well as some top Makefile variables.
Fixed the BUGS file with respect to using `make debug`.
Added a final ls of `debug.out` for `make debug`.
Test if the arch value (`uname -p`) is "powerpc".
PowerPC based systems no longer try to use xcrun to determine where
things like INCDIR (include files) are located.
The following are the changes in this release:
Added cal/fnv_tool.cal, a calc resource file defining:
find_fnv_prime(bits)
deprecated_fnv0(bits,fnv_prime,string)
fnv_offset_basis(bits,fnv_prime)
fnv1a_style_hash(bits,fnv_prime,prev_hash,string)
Fixed sorted order of cal/README.
The following are the changes in this release:
Ported calc to the s390x IBM Mainframe running RHEL9.1.
Added cal/splitbits.cal:
splitbits(x, b)
Given an integer x, split the value into a list of integers,
each of which is at most b bits long.
The value b must be an integer > 0.
The number of elements in the returned list is:
ceil((highbit(x) + 1) / b)
If x == 0, then a list of 1 element containing 0 is returned.
If x < 0, then the two's compliment of abs(x) is returned.
Even though calc represents negative integers as positive values
with sign bit, the bits returned by this function are as if
the integer converted as if the integer was a two's compliment value.
See also the help command:
; help resource

Fixed obsolete references to the atoz() in LIBRARY to use the
correct internal function name of str2z().
Fixed obsolete references to the atoq() in LIBRARY to use the

Document in help/unexpected that * operator has has a higher
precedence than << in calc, which differs from C. Thanks
goes to GitHub user @inguin for pointing put this difference.
Fixed obsolete references to the atoz() in LIBRARY to use the
correct internal function name of str2z().
Fixed obsolete references to the atoq() in LIBRARY to use the

covered under "The Unlicense" (see https://unlicense.org):
sha1.c
sha1.h
cal/dotest.cal
cal/screen.cal
Updated help/credit to match the above changes to COPYING.

LDFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
CALC_ENV+= ASAN_OPTIONS=detect_stack_use_after_return=1
Improved how pointers to functions are declared for the builtins
array in func.c to avoid function declarations without a prototype
that is now deprecated in C.
Improved how pointers to functions are declared for the opcodes
array in opcodes.c to avoid function declarations without a prototype
Replaced use of egrep with grep -E in Makefiles.
Fixed cases where variables were set but not used in symbol.c, calc.c,
and the main function in func.c as used by funclist.c.
Added rule name to "DO NOT EDIT -- generated by the Makefile" lines
in constructed files.
Test if <sys/vfs.h> exists and set HAVE_SYS_VFS_H accordingly
in have_sys_vfs.h. Added HAVE_SYS_VFS_H to allow one to force
this value.
Test if <sys/param.h> exists and set HAVE_SYS_PARAM_H accordingly
in have_sys_param.h. Added HAVE_SYS_PARAM_H to allow one to force
this value.

accordingly in have_statfs.h. Added HAVE_STATFS to allow one
to force this value.
The pseudo_seed() function will also try to call statfs() if
possible and permitted by the HAVE_STATFS value.
Test if makedepend command is available before trying to build
the Makefile dependency list via "make depend".

The following are the changes in this release:
Fixed missing <string.h include in have_fpos_pos.c.
Change calc version from 2.14.1.2 to 2.14.2.3 as part of a test to
build calc RPMs on a reference RHEL8.7 platform (formerly a RHEL7.9
platform).
Otherwise, the probe result changes with compilers which do not
support implicit function declarations, a language feature that
was removed from C in 1999.
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("complex_space", boolean). The "complex_space" controls
whether or not a space (' ') is printed before and after the + or -
in complex values.
By default, config("complex_space") is false.
For example, with the default, config("complex_space", 0):
; asin(2)
1.57079632679489661923-1.31695789692481670863i
With config("complex_space", 1):
; asin(2)
1.57079632679489661923 - 1.31695789692481670863i
NOTE: Use of config("complex_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("complex_space", 1) can break printing and scanning
of complex values via "%c".
Added config("complex_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("complex_space").
Clarify in the calc man page, the relationship between -q and
calc start scripts such as the ~/.calcrc file.
Fixed in the calc man page, the issue of -f not implying -q.
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("fraction_space", boolean). The "fraction_space" controls
whether or not a space (' ') is printed before and after fractions.
By default, config("fraction_space") is false.
For example, with the default, config("fraction_space", 0):
; base(1/3),
; 1/7
1/7
With config("fraction_space", 1):
; base(1/3),
; 1/7
1 / 7
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of complex values via "%c".
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("tilde_space", boolean). The "tilde_space" controls
whether or not a space (' ') is printed after leading tilde ('~').
By default, config("tilde_space") is true, which is a change
from past behavior. For example, now:
; 1/3
~ 0.33333333333333333333
With config("tilde_space", 0):
; 1/3
~0.33333333333333333333
To disable "tilde_space", use config("tilde_space", 0) on the
command line and/or use config("tilde_space", 0),; in your ~/.calcrc.
Thanks goes to <GitHub use ljramalho> for this suggestion.
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space") and to account for the new default.
In pseudo_seed(), we removed a call to setjmp() that was only
there to add more information to mix into the seed. For compilers
such as gcc that used -Wclobbered, the call to setjmp() gave the
impression that the hash_val might be clobbered by a longjmp().
Where there is no longjmp() that would use the previous setjmp(),
the gcc compiler has nil ways to notice that. So to avoid confusion
we removed the setjmp() call. Thanks to <GitHub user mattdm> for
raising this potential concern.
In find_tty_state(), we changed how we expand fd_orig as an original
pre-modified copy of fd_setup. We realloc the fd_orig array and copy
the fd_setup into it first, before touching the fd_setup array.
Fixed a -Wuse-after-free warning that identified a call to realloc() in
find_tty_state() could move the fd_setup array. Thanks goes to <GitHub
user mattdm> for reporting this bug!
The following are the changes in this release:
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
is defined).
Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was
NOT related to fgetpos & fsetpos but rather if we we have an __pos
element in FILEPOS.
Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
Improved comments in have_fpos_pos.h to show why and how
HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
Changed showfiles builtin to print sizes cast to (long int) with
the "%ld" printf format to avoid implementations that do not support
the "%lld" printf format specifier.
Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H
to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall
rules remove the any old have_fpos.h that was previously installed.
Added swap_HALFs(dest, src, len) function to byteswap.c.
Calc can now handle Big Engian file position sizes that are a
multiple of BASEB bits in length. Before handle Big Engian file
positions could only be 32 and 64 bits in length. This will allow,
for example, a Big Engian file position size of 128 (assuming that
128/BASEB is is an integer).
Temporary workaround for musl libc systems such as gentoo Linux that
allows them to compile calc and successfully run the regression test.
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little

Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H
to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall

"%lld" printf format specifier.
Added full_debug rule to Makefile. This does the work of the
old debug rule in a more verbose mode by using Q= H=@ S= E= V=@.
The debug rule in the Makefile now pre-removes debug.out and then
runs make full_debug sending stdout and stderr to debug.out. It then
prints a few instructions about filing a GitHub issue bug report.
The following are the changes in this release:
Added a few remarks on calc version numbers to version.c.
Fixed how fposval.h is built. On a number of systems, the fposval.c
file failed to compile incorrectly. This caused problems for systems in
which fposval.h.def was not correct.
Fixed how have_memmv.h is built. On a number of systems, the have_memmv.c
file failed to compile incorrectly, producing a potentially incorrect
have_memmv.h file for such systems.
Fixed how align32.h is built. On a number of systems, the align32.c
file failed to compile incorrectly, producing a potentially incorrect
align32.h file for such systems.

Fixed how have_strlcat.h is built. On a number of systems, the have_strlcat.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcat.h file for such systems.
Fixed how have_strlcpy.h is built. On a number of systems, the have_strlcpy.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcpy.h file for such systems.
Fixed how have_uid_t.h is built. On a number of systems, the have_uid_t.c
file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.

file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.
Fixed a \-escape bug in calc(1) man page.
Added cal/comma.cal:
Convert numbers into strings with 3-digit group and integer-fraction
separators.
If the value is an integer, the integer-fraction separator is not used.
str_comma(x, [group, [decimal]])
Convert x into a string.
If group is given and is a string, group will be used as
the 3-digit group separator, otherwise the default 3-digit
group separator will be used.
If decimal is given and is a string, group will be used as
the integer-fraction separator, otherwise the default
integer-fraction separator will be used.
The decimal and group arguments are optional.
set_default_group_separator(group)
Change the default 3-digit group separator if group is a string,
otherwise the default 3-digit group separator will not be
changed. Return the old 3-digit group separator.

The value produced by str_comma() is returned.
The following are the changes from calc version 2.14.1.0 to date:
Fixed alignment of show item section of help command.
Bug fix: While 0^0 == 1, now for y > 0, 0^y == 0.
Adjusted cal/test8900.cal to reflect this bug fix.
Added tests to cal/regress.cal to help verify bug fix is fixed.
While 0^0 == 1, now for y > 0, 0^y == 0.
Adjusted cal/test8900.cal to reflect the this bug fix.
Added tests to cal/regress.cal to help verify bug fix is fixed.
Changed /*NOTREACHED*/ to not_reached(); and use "attribute.h".
Added .PHONY rule, just after all rule, to Makefiles.
Fixed an improper indentation issue.
Expanded the globalsymbol string table size: from 1024 to 65536.
Expanded the how often to reallocate string table is performed:
from 100 to 1024.
Expanded the number env_pool elements to allocate at a time:
from 10 to 256.
Improve comments on Makefile.local and add a few more examples
of how it might be used.
Changed Makefile to set shell before setting the SHELL Makefile
variable.
Added text to HOWTO.INSTALL to help people with systems that
lack the readline package.
Trimmed long line in the CONTRIBUTING.md file.
The following are the changes in this release:
Fixed typo in Makefile.local comment.
Established a tagging procedure for a production release.
Production git tags will be of the form:
prod-2.x.y.z
We apologize for the calc v2.14.0.12 source tarball that was missing
critical files. While the executable was well tested, our release
process was deficient.
We are improved our release process and added tests during the release
procedure to help verify that we are not regressing in to the
"v2.14.0.12 source tarball" issue, among other things.
Depending on how things do, you might is several releases come out over
a short period of time. The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
Removed constructed help file that incorrectly added as a src file.

The following are the changes in this release:
Made major changes to our release process in order to avoid
missing critical files that happened in calc v2.4.0.12.
Minor tweak to seed() builtin. Updated help/srand and help/srandom.
Moved Makefile.ship into Makefile.
Removed custom/Makefile.head and custom/Makefile.tail.
The custom/Makefile is now part of source and includes Makefile.
In particular, custom/Makefile makes use of the 'middle' of
the new top level Makefile where calc's top level Makefile
variables are defined.
Makefile.simple and custom/Makefile.simple are now part of the source
and are constructed from Makefile and custom/Makefile respectively.
The Makefile.simple and custom/Makefile.simple avoid using GNU
conditionals. They may be used with older/classic make commands.
Makefile.local will include comments about how to better use
it. Between releases, Makefile.local at the top of the master branch
will contain how we typically build calc and test calc (FYI: we
normally enable things such as -Werror -Wextra -pedantic). When we
push out a release, Makefile.local will be stripped of non-comment
lines. Thus, releases of calc, and, released "calc*.src.rpm"
files and the source tarballs, will have a Makefile.local with
only comments.
The "README.*" files and "HOWTO.INSTALL" file have been updated.
By default, compiler warnings have been turned up. The Makefile
variable ${CCWARN} now defaults to:
CCWARN= -Wall -Wextra -pedantic
The previous level of compiler warnings can be easily restored by
adding to Makefile.local:
CCWARN:= -Wall
The readline, history and ncurses libraries are now default.
The Makefile variables ${USE_READLINE}, ${READLINE_LIB}, and
${READLINE_EXTRAS} now default to:
USE_READLINE= -DUSE_READLINE
READLINE_LIB= -lreadline
READLINE_EXTRAS= -lhistory -lncurses
The previous mode where readline, history and ncurses libraries
were not compiled in by default can be easily restored by

a short period of time. The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
We made several changes to the Makefiles. We also added a new
README.RELEASE document (see "help release") that is a work in
progress. Along the way we discovered a few things that needed to be
updated in documentation.
See the CHANGES file for details.
The following are the changes in this release:
Fixed a number of typos.
Drop support for SunOS, IRIX and MINGW32_NT-5.0 targets.
Drop support for CLOCK_SGI_CYCLE. Drop testing for __MSDOS__.
Minor improvement of various help files. Made format of help
files more consistent.
Corrected a few comments in zrandom.c, including a case where
the comment referred to 1007 when it should have used 2^32.
Improved seed() generation. Improved some comments in seed.c.
Added have_environ.c to build have_environ.h in order to
determine if:
extern char **environ; /* user environment */
is an valid external symbol.
Fixed documentation that referred to the old additive 55
generator. We have been using the subtractive 100 in place
of the additive 55 generator for a while now.
Fixed depend rule for custom/Makefile.
Fixed how Makefile variable SHELL is set on macOS vs. Linux.
Using /bin/sh on macOS due to how zsh treats globs by default.
Added charbit.h to define CALC_CHARBIT which is either CHAR_BIT
from <limits.h> or 8 or a value set by the Makefile variable
CALC_CHARBIT. Added have_limits.h to determine if <limits.h>
is a system include file.
Compiling now tests for _WIN64 as well when testing for _WIN32.
Now assuming that <stdio.h> is available under _WIN32 and _WIN64.
Added some preliminary notes about attempts to compile calc
under Windows 11.
BTW: While we are unable to use Windows 11, we welcome
Windows 11 developers to try compiling calc natively
(instead of via a Linux virtual machine). If you are
able to compile Windows 11 natively, we would welcome
GitHub pull requests showing any needed modifications:
https://github.com/lcn2/calc/pulls
Please also add notes to the 'Compiling calc under Windows 11'
section in README.WINDOWS file.
We added Makefile.simple as part of the master branch source
to help those who may be using a make tool that does not support
GNU Make-like features such as "ifeq" and ":=".
Fixed incorrect ustat_dev member ref in seed() builtin that
was part of the unreleased calc v2.12.0.11.

determine if:
extern char **environ; /* user environment */
is an valid external symbol.
The constants:
9, 9/10, 10/9, 24, 360, 400
are used by func.c only, so there were moved
from {q,z}math.{c,h} to func.c.
The constants:
3, 4
are used by zrandom.c only, so there were moved
from {q,z}math.{c,h} to zrandom.c.
Improved the way that internal pre-defined constants are managed.
Removed unused internal pre-defined constants. Added code to
prevent an internal pre-defined constant (that was never
allocated) from being freed.
The following are the changes in this release:
Due to issues with clang and Apple Silicon, ARCH_CFLAGS is now,
by default, empty:
ARCH_CFLAGS=
If you want to use, say, -march=native, then either change
the Makefile or make with:
make all ARCH_CFLAGS='-march=native'
Added arch and hardware as GNU Makefile computed values.
As with ${target}, ${arch} and ${hardware} is computed by uname:
target: uname -a
arch: uname -p
hardware: uname -m
Fixed compiling calc on Apple Silicon with homebrew. On Apple
Silicon, HomeBrew installs on into a different location. The
Makefile checks if ${hardware} is arm64 and adjusts the location
of libraries such as readline and history accordingly.
The following are the changes in this release:
Fizzbin is a better word. :-)
The help and man builtin commands now return an error when a
help file cannot be opened, such as when there is no help file.
Added palindrome.cal resource file. For example, to find the
largest (highly probable) prime palindrome under 280 decimal
digits (text tweet limit):
prevprimepal(1e280)
In cal/palindrome.cal:
Improved the performace of nextpal() and nextprimepal()
by adding and using palnextpal().
Improved the performace of prevpal() and prevprimepal()
by adding and using palprevpal().
Test showed that runs that took 0.0530 cpu seconds can
now be done in as little as 0.0327 cpu seconds.
The help and man commands now issue an error message when
the help file cannot be opened: say because there is a
help command typo and there is no such help file.
The following are the changes in this release:
Fixed typo in cal/statistics.cal thanks to a report by <GitHub user
dennisaldea>.
Fixed an old Windoz pun in README.WINDOWS as requested by <GitHub
user marcodegio>.
Fixed a really obscure bug in the internal initconstants()
function of const.c that has been sitting for over 31 years!
We are amazed that nobody has encountered this bug before
now. Nevertheless, our very extensive regression and
multi-architecture testing found the bug. Now, after all
those years, it is fixed.
Fixed issues identied by the default CodeUL GitHub security code scan:
Wrong type of arguments to printf in have_fpos_pos.c
Multiplication result converted to larger type in zfunc.c

d2dms(degs, d, m, s [,rnd]) - given degs, compute d, m, s
d2dm(degs, d, m [,rnd]) - given degs, compute d, m
See help/d2dms and help/d2dm.
Example:
; print d2dms(360.321,deg=,min=,sec=), deg, min, sec;
0.321 0 19 15.6
; print d2dm(360.321,deg=,min=), deg, min;
0.321 0 19.26
Added builtin functions to convert between gradians and
gradians, minutes and seconds under the config("mod")
round rules:
g2gms(grads, g, m, s [,rnd]) - given grads, compute g, m, s
g2gm(grads, g, m [,rnd]) - given grads, compute g, m
See help/g2gms and help/g2gm.
Example:
; print g2gms(400.321,grad=,min=,sec=), grad, min, sec;
0.321 0 19 15.6
; print g2gm(400.321,grad=,min=), grad, min;
0.321 0 19.26
Added builtin functions to convert between hours and
hours, minutes and seconds under the config("mod")
round rules:
h2hms(hours, h, m, s [,rnd]) - given hours, compute h, m, s
h2hm(hours, h, m [,rnd]) - given hours, compute h, m
See help/h2hms and help/h2hm.
Example:
; print h2hms(24.321,hour=,min=,sec=), hour, min, sec;
0.321 0 19 15.6
; print h2hm(24.321,hour=,min=), hour, min;
0.321 0 19.26
In addtion:
Renumbered regression tests 3408 thru 3437, to 9102 thru 9131.
Updated Added hms.cal resource file to use h2hms() builtin.
Updated Added dms.cal resource file to use d2dms() builtin.
Fix minor typo in help/mod SYNOPSIS.
Fix minor typo in help/quo SYNOPSIS.
Added a few more examples to help/strcmp.
The clean and clobber makefile rules no longer list custom/Makefile
as a dependency.
Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended. Sorry (tm Canada) :)
Fixed a few typos in CHANGES.
As a side note: We stayed v2.13.x was kept for only a short time.
The move to 2.14.x was motivated by non-compatible changes due to
the default order of CALCRC, plus some new builtin functions.
More changes are likely, so we might see another v2.14.0.x release
before things are declared "recommended stable".
Not that we wan to discourage people from trying v2.14.0, you should
try it. We just want things to become stable and well field tested
before we reach the "recommended stable" release state.
Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended. Sorry (tm Canada) :)
A .bak file was accicently put into the DETAIL_HELP list.
That bogus help file was removed.
Modified the help/Makefile detail_help_list rule to remove .bak files
when forming DETAIL_HELP.
Updated CHANGES.
Updated help/unexpected.
Added help files for d2g(), d2r(), g2d(), g2r(), r2d(), r2g().
Added regression test code for the same functions.
Fixed a few minor typos.

The :-separated default CALCRC value has been reversed.
The default CALCRC was:
${CALC_SHAREDIR}/startup:~/.calcrc:./.calcinit
The default CALCRC is now:
./.calcinit:~/.calcrc:${CALC_SHAREDIR}/startup
See "help environment" for details.
Added engineering mode as per a GitHub pull request from
<GitHub user heitzmann>. Thank you! For example:
; config("mode","eng"),
; 10^41
100e39
or for example:
; base(1000),
; 2^23209-1
~402.87411577898877818187e6984
For more information see:
help base
Added regression test code for engineering mode. Improved and
expanded regression test code related to the base() and base2()
builtin functions.
Fixed a critical bug in the above mentioned pull request where
a call to base2(1000) would make calc unstable and likely to
dump core.
The :-separated default CALCRC value has been reversed.
The default CALCRC was:
${CALC_SHAREDIR}/startup:~/.calcrc:./.calcinit
The default CALCRC is now:
./.calcinit:~/.calcrc:${CALC_SHAREDIR}/startup
See "help environment" for details.
Similar to scientific mode, engineering mode also displays numbers in
base 10 exponential notation, with the difference that exponents are
always multiples of 3, to facilitate the interpretation in terms of
SI prefixes.
The mode is activated in config thru "engineering" or "eng. For base
and base2, it uses the special value 1000.
Replaced /usr/local with the use of ${PREFIX} in calc Makefiles.
The ${PREFIX} is not the same as ${T}. The ${T} specifies
a top level directory under which calc installs things.
While usally ${T} is empty, it can be specific path
as if calc where "chrooted" during an install.
The ${PREFIX} value, during install, is a path between
the top level ${T} install directory and the object
such as an include file.
Corrected a few more typos in Makefile comments.
Added Makefile.local, a file with a single comment. The main
Makefile includes Makefile.local just before the first all rule.
One may overtide any Makefile setting by modifying Makefile.local.
For example, Makefile.local could force BLD_TYPE:
HAVE_STRING_H:= YES
HAVE_TIMES_H:= YES
SED:= /usr/local/bin/nsed
Added ${LOC_MKF} to specify the make of the file that is
included just before the all file. So one could place
the above override lines into a different file and call
make changing the ${LOC_MKF} value. For example:
make LOC_MKF=Makefile.private clobber all chk
Updated HOWTO.INSTALL to mention Makefile.local.

Corrected a few more typos in Makefile comments.
The following are the changes in this release:
Fixed typo (missing quotes) in the env rule.
Fixed intendation problem in CHANGES.
Combined 2.12.9.1 changes into the 2.12.8.2 to 2.12.9.0
range, and thus renamed the range to 2.12.8.2 to 2.12.9.1.
Fixed issues related to building Makefile.simple.
Fixed how the Makefile variable MANPATH is set for macOS.
Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
Fixed how the calc(1) man page is installed under macOS.
Fixed how calc man page in ${CATDIR} is formed.
Fixed how Makefile.simple is formed.
Fixed the #! calc script argument processing. The initial #!
line must end in a -f. For example, if calc is in /usr/local/bin/calc,
then the following would be the first line of a calc script:
#!/usr/local/bin/calc -f
...
It is common that -q be usde with a calc script, so assuming the
same /usr/local/bin/calc path:
#!/usr/local/bin/calc -q -f
...
Use of -s in the #! first line of a calc script is not needed
since -f implies -f.
The argv() will now return values more typical of C's main().
Before it returned one less than the number of arguments. Now,
for example, when calc is given 2 args, argv() will return 3.
The value of argv(0) will be the path to calc, or in the
case of a #! calc cscript, it will return the name of the script.
Updated the calc man page and help/argv to reflect the
above changes.
Improved the formatting of the calc man page.
Fixed the formation of the win32 sub-directory via the win32_hsrc
Makefile rule.
Due to incompatible changes to the argv() function, and #! calc
scripts, we are setting the version to the next minor number:
2.13.0
Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
Fixed intendation problem in CHANGES.
Combined 2.12.9.1 changes into the 2.12.8.2 to 2.12.9.0
range, and thus renamed the range to 2.12.8.2 to 2.12.9.1.
The following are the changes in this release:
Fixed a typo typo in help/Makefile that caused the build of
2.12.9.0 to fail in a number of cases. Thanks to a report by
<GitHub user balducci>.
Pass form Makefile variables ${Q}, ${S}, ${E}, ${H} and ${V} down
to all sub-directory Makefiles from the top level Makefile.
Added notes to help/unexpected about:
display() will limit the number of digits printed after decimal point
%d will format after the decimal point for non-integer numeric values
%x will format as fractions for non-integer numeric values
fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish
Fixed Makefile dependencies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
Improved the messages produced by the depend in the Makefiles.
Changed the UNUSED define in have_unused.h to be a macro with
a parameter. Changed all use of UNUSED in *.c to be UNUSED(x).
Removed need for HAVE_UNUSED in building the have_unused.h file.
CCBAN is given to ${CC} in order to control if banned.h is in effect.
The banned.h attempts to ban the use of certain dangerous functions
that, if improperly used, could compromise the computational integrity
if calculations.
In the case of calc, we are motivated in part by the desire for calc
to correctly calculate: even during extremely long calculations.
If UNBAN is NOT defined, then calling certain functions
will result in a call to a non-existent function (link error).
While we do NOT encourage defining UNBAN, there may be
a system / compiler environment where re-defining a
function may lead to a fatal compiler complication.
If that happens, consider compiling as:
make clobber all chk CCBAN=-DUNBAN
as see if this is a work-a-round.
If YOU discover a need for the -DUNBAN work-a-round, PLEASE tell us!
Please send us a bug report. See the file:
BUGS
or the URL:
http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html
for how to send us such a bug report.
Added the building of have_ban_pragma.h, which will determine
if "#pragma GCC poison func_name" is supported. If it is not,
or of HAVE_PRAGMA_GCC_POSION=-DHAVE_NO_PRAGMA_GCC_POSION, then
banned.h will have no effect.
Fixed building of the have_getpgid.h file.
Fixed building of the have_getprid.h file.
Fixed building of the have_getsid.h file.
Fixed building of the have_gettime.h file.
Fixed building of the have_strdup.h file.
Fixed building of the have_ustat.h file.
Fixed building of the have_rusage.h file.
Added HAVE_NO_STRLCPY to control if we want to test if
the system has a strlcpy() function. This in turn produces
the have_strlcpy.h file wherein the symbol HAVE_STRLCPY will
be defined, or not depending if the system comes with a
strlcpy() function.
If the system does not have a strlcpy() function, we
compile our own strlcpy() function. See strl.c for details.
Added HAVE_NO_STRLCAT to control if we want to test if
the system has a strlcat() function. This in turn produces
the have_strlcat.h file wherein the symbol HAVE_STRLCAT will
be defined, or not depending if the system comes with a
strlcat() function.
If the system does not have a strlcat() function, we
compile our own strlcat() function. See strl.c for details.
Fixed places were <string.h>, using #ifdef HAVE_STRING_H
for legacy systems that do not have that include file.
Added ${H} Makefile symbol to control the announcement
of forming and having formed hsrc related files. By default
H=@ (announce hsrc file formation) vs. H=@: to silence hsrc
related file formation.
Explicitly turn off quiet mode (set Makefile variable ${Q} to
be empty) when building rpms.
Improved and fixed the hsrc build process.
Forming rpms is performed in verbose mode to assist debugging
to the rpm build process.
Compile custom code, if needed, after main code is compiled.
Fixed Makefile dependenies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
The SWAP_ macros already write the result to their destination arg, so
there's no need for an extra assignment -- and this is undefined
behaviour because there are two assignments to the same variable without
an intervening sequence point (as GCC 10 correctly warns).
The following are the changes in this release:
Calc can now correctly compile without CUSTOM being defined,
thanks to a report by <GitHub user barsnick>.
Fixed how the *.tar.bz2 are formed. The calc-2.12.8.0.tar.bz2 file
that was formed for calc version 2.12.8.0 was missing most files.
Expanded 'make chk' to also verify that 'make distchk' and 'make
distlist' execute successfully. This will help check a regression
of the bug that produced the bogus calc-2.12.8.0.tar.bz2 file.
Added additional regression tests related 0^(zero_expression)==1.

Fixed a mistake in "help intro" where some inserted text changed
the value of "." and thus made the next result incorrect.
Clarified in "help factor" that 1 is returned if no
factor below the limit was found.
Removed Makefile variable ${MAKEFILE_REV}.
The missing cscript/square.calc file has been restored.
Fixed compiler errors and warnings related to GCC. In particular,
gcc/9.3.1 and gcc/10.2.1 now compile calc without any compiler
errors or warnings, even with -Werror -Wextra -pedantic.
To print out information about the calc compilation
environment, we added the following make rule:
make calcinfo
Improved how 'make debug' operates.
Moved help/contrib to CONTRIB-CODE. The help/contrib file
is now build from a copy of CONTRIB-CODE.
Created a new calc bug report Email address. Created a new
calc question Email address. Created a new calc contribution
Email address. See the BUGS file for details.
Added "help questions" to print the QUESTIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the directory by the $CALCHISTFILE
environment variable.
If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the directory
by the $CALCCUSTOMHELP environment variable.
Fixed a number of typos in text and in source code comments.

Calc as defined 0^0 as 1. However in the past, 0 raised to
an expression that evaluted to zero returned 1. The result
was that 0^0 was different than 0^(6-6) or even 0^(0).
Now, calc will return 1 for 0^(0) and 0^zero when zero == 0.
By default, the calc history file is located in ~/.calc_history.
Now, if the environment variable $CALCHISTFILE is defined
and is non-empty, then calc history file will be defined
by the $CALCHISTFILE environment variable.
These changes are per calc version 2.12.7.3:
Requiring calc shell scripts to use -s -f at the end of the
initial #! line.
Fixed /tmp/mersenne example in calc(1) man page.
Added make variable ${ARCH_CFLAGS}. The ${ARCH_CFLAGS} is
added after ${CCMISC} and before ${EXTRA_CFLAGS} when building
the ${CFLAGS} for compiling C code. are ${CC} when compiling
C files. The default value is:
ARCH_CFLAGS= -march=native
which directs C compiler to compile for the native machine.
To disable use of '-march=native', set ARCH_CFLAGS to the empty
string as in:
make all ARCH_CFLAGS=
To make calc RPMs more portable, they are compiled with an
empty ARCH_CFLAGS.
These changes are per calc version 2.12.7.4:

GCC 7 Added a warning for implicit fallthroughs in switch cases.
It's enabled by -Wextra, and treated as an error due to -Werror so
compilation fails on GCC 7 and higher.
See -Wimplicit-fallthrough in the GCC manual.
Corrected CHANGES notes that were mixed up for TAB, VT, CR &
NL. The code in 2.12.7.0 is correct. The CHANGE notes should
have read:
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0a in ASCII encoding
\r return byte 0x0d in ASCII encoding
\t tab byte 0x09 in ASCII encoding
\v vertical tab byte 0x0b in ASCII encoding
Sorry!
The following are the changes from calc version 2.12.7.0 to date:
Added a patch to replaces the manual search for include files
in $(INCDIR) in the have_*.h targets with compiler invocations.
Thanks goes to Helmut Grohne (helmut at subdivi dot de) who
implemented the patch and posted it to the Debian bug tracker
and Martin Buck (m at rtin-buck dor de) for forwarding it to us.
The check_include make rule was fixed to not assume /usr/include.
The qprintnum() function now takes outdigits as a 3rd argument.
Most of the time, this 3rd argument is just conf->outdigits.
But when it comes to the experimental '%g', this value can
change. This avoids having to modify conf->outdigits.
Fixed a problem where gcc complains about E_FUNC not being defined
for Linux systems as reported by Martin Buck (m at rtin-buck dor de).
Updated the help files help/config, help/display, help/epsilon,
help/fprint, help/printf, and help/strprintf to give more
examples of how display digits and epsilon precision interact
with displaying values.
Added more information about %g in the help file help/printf.
The '\a' is now recognized in a printf format string as the
single byte audible bell character (byte 0x07 in ASCII encoding).
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0b in ASCII encoding
\r return byte 0x0a in ASCII encoding
\t tab byte 0x0d in ASCII encoding
\v vertical tab byte 0x09 in ASCII encoding
Regularized the case statements in qio.c, str.c, and token.c
that relate to escape characters.

This code %g is preliminary.
Fixed some code style issues to match the current code style.
Added regression tests and help file updates to printf and strprintf.
Fixed use of magic number -4: using -P instead.
Noted two problem areas with XXX comments in qio.c:
1) need a qprintfg function
2) re-write to not modify conf->outdigits
The following are the changes in this release:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
Fixed some compiler warnings, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Added work around for a gcc warning bug, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Fixed errors in various help files such as:
mat randbit seed srandom types
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.
Increased TTYSIZE (reallocation size for terminal buffers) from 100 to 8191.
Increased MAXDEPTH (maximum depth of input stack) from 10 to 255.
Increased interactive input buffer size from 1024 to 256k. This has the
effect of increasing the maximum length of an input line from a tty.
This helps with an interactive bug that was reported by Ruslan Kabatsayev
(b7 dot 10110111 at gmail dot com).
The calc man page indicates that -d also disables the printing of the
leading tilde.
Added information to "help command" about how to silence messages
while reading calc resource files.
Fixed an error message buffer overflow thanks to a report by
Frank Peters <nlp at northernlightsphoto dot biz>.
Replaced all use of the C funcion sprintf() with snprintf().
Replaced all use of the C funcion vsprintf() with vsnprintf().
Replaced all DONT_HAVE_VSPRINTF with DONT_HAVE_VSNPRINTF.
Replaced all Makefile var ${HAVE_VSPRINTF} with ${HAVE_VSNPRINTF}.
Fixed errors in various help files such as:
mat randbit seed srandom types
