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)
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
The following are the changes in this release:
Added builtin functions to convert between degrees and
degrees, minutes and seconds under the config("mod")
round rules:
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
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.
Added builtin functions to convert between degrees, minutes and
seconds and degrees under the config("mod") round rules:
dms2d(d, m, s [,rnd]) - convert deg, min, and secs to deg
dm2d(d, m [,rnd]) - convert deg, min to deg
See help/dms2d and help/dm2d.
Example:
; print dms2d(12, 20, 44.16);
12.3456
; print dm2d(3601, -25.5594);
0.57401
Added builtin functions to convert between gradians, minutes and
seconds and gradians under the config("mod") round rules:
gms2g(g, m, s [,rnd]) - convert grad, min, and secs to grad
gm2g(g, m [,rnd]) - convert grad and min to grad
See help/g2gms and help/g2gm.
Example:
; print gms2g(12, 20, 44.16);
12.3456
; print gm2g(4001, -25.5594);
0.57401
Added builtin functions to convert between hours, minutes and
seconds and hours under the config("mod") round rules:
hms2h(h, m, s [,rnd]) - convert hours, min, and secs to hours
hm2h(h, m [,rnd]) - convert hours, min to hours
See help/hms2h and help/hm2h.
Example:
; print hms2h(12, 20, 44.16);
12.3456
; print hm2h(241, -25.5594);
0.57401
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) :)
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.
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.
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 ...
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 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 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 compliation
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 QUESIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the direcgory 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 direcgory
by the $CALCCUSTOMHELP environment variable.
The calc-tester mailing list has been retired. See:
* How to submit a calc bug report:
http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html
* How to contribute code to calc:
http://www.isthe.com/chongo/tech/comp/calc/calc-contrib.html
* How to submit a question about calc:
http://www.isthe.com/chongo/tech/comp/calc/calc-question.html
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:
Fixed issues relating to compiling on macOS. Fixed issues
where <unistd.h> is needed.
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

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
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.

Fixed a man page warning about ./myfile where the leading dot
was mistook for an nroff macro. Thanks goes to David Haller
<dnh at opensuse dot org> for providing the patch.
Improved gen_v1(h,n) in lucas.cal for cases where h is not a
multiple of 3. Optimized the search for v(1) when h is a
multiple of 3.
Fixed a Makefile problem, reported by Doug Hays <doughays6 at gmail
dot com>, where if a macOS user set BINDIR, LIBDIR, CALC_SHAREDIR
or INCDIR in the top section, their values will be overwritten by
the Darwin specific section.
Added the makefile variable ${COMMON_ADD} that will add flags
to all compile and link commands. The ${COMMON_ADD} flags are
appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}. This
facility is available to nearly all platforms except those with
very old make comamnds that do not understand the += operator.
Example on masOS (Darwin), one may invoke clang's -fsanitize
facility by:
make clobber all COMMON_ADD='-fsanitize=undefined -fsanitize=address'
Another example. To force C warnings to be treated as errors:
make COMMON_ADD='-Werror'
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
calc GitHub philosophy
All of the previous commits in the master branch are the consists
of compressed source tarballs. The 125 git tags represent calc
releases from version 2.10.2t30 (Sat Jul 06 1996 04:17:00 GMT-0700)
to version 2.12.5.6 (Sun May 21 2017 15:03:29 GMT-0700).
At this point master branch will switch from those released tarballs
to the development tree. While we will make an effort to verify
that commits won't break calc: sometimes we will end up breaking
calc. You should consider the top of the master branch as potentially
unstable.
When we are ready to release calc, we will tag the commit with the
calc version and submit a release on GitHub. The GitHub release
will contain the usual RPMs, SRPMs, a release README and a released
source tarball.
