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.
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".
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.
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).
Sort .gitignore. Add calc.spec to .gitignore.
Update format of header part of Makefiles.
Modify calc.spec.in to handle dynamic shared libraries with 3-digit
version numbers.
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.
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.
Updated COPYING file to indicate that these files are now
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.
Updated CONTRIB-CODE and calc.man to refer to using GitHub pull requests
for contributing to calc (instead of using Email).
Updated BUGS and calc.man to refer to using GitHub issues
for reporting calc bugs (instead of using Email).
Updated QUESTIONS and calc.man to refer to using GitHub issues
for asking calc questions (instead of using Email).
Fixed Makefile.local command example to refer to overriding the
Makefile variable DEBUG (instead of CDEBUG).
Fixed all make chk ASAN warnings under macOS 13.2.1 when calc is compiled
with the following uncommented lines in Makefile.local:
DEBUG:= -O0 -g
CFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
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.
Test if <sys/mount.h> exists and set HAVE_SYS_MOUNT_H accordingly
in have_sys_mount.h. Added HAVE_SYS_MOUNT_H to allow one to force
this value.
Test if the system as the statfs() system call and set HAVE_STATFS
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.
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.
Changed /*NOTREACHED*/ to not_reached(); and use "attribute.h".
Added .PHONY rule, just after all rule, to Makefiles.
Fixed an improper indentation issue.
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:
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
adding to Makefile.local:
USE_READLINE:=
READLINE_LIB:=
READLINE_EXTRAS:=
We have renamed "stable" as "production".
We have renamed "unstable" as "tested".
On the web site:
http://www.isthe.com/chongo/src/calc/
these files has been renamed:
2.x.y.z_IS_LATEST_STABLE ==> 2.x.y.z_IS_LATEST_PRODUCTION
2.x.y.z_IS_LATEST_UNSTABLE ==> 2.x.y.z_IS_LATEST_TESTED
The terms 'stable' and 'unstable' were both misleading and
inaccurate. For details see the new documention file:
README.RELEASE
See also the help command:
; help release
Fixed bug impacting how have_ustat.h was formed.
Updated help/archive to reflect GitHub use.

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.
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.
Drop support for CLOCK_SGI_CYCLE.
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.
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
Added several conversion functions:
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
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.
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.
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.
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 ...
