Removed use of HAVE_MEMMOVE as well have_memmv.c. Removed the
building and including of have_memmv.h. Removed the memmove()
function in blkcpy.c, used when HAVE_MEMMOVE was NOT defined.
The libc memmove(3) function as defined by <string.h> is now
required to compile calc because the replacement code in
blkcpy.c q was problematic, especially when regions overlap.
The HAVE_MEMMOVE make symbol was removed from Makefile.config.
Thanks to GitHub user @skeeto for reporting this problem.
Change Makefile.config to, if not using not HomeBrew, then try to
detect macports and/or using /opt/local/{lib,include}.
Changed version from 2.15.1.0 to 2.15.1.1.
Put full date range (1989-2025) of calc source into version.h.
Converted all ASCII tabs to ASCII spaces using a 8 character
tab stop, for all files, except for all Makefiles (plus rpm.mk).
The `git diff -w` reports no changes.
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.
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.

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.
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.
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.
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.
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:
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
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.
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.
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".
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.
