calc: C-style arbitrary precision system / News: Recent posts

The following are the changes in this release:

Converted all ASCII tabs to ASCII spaces using a 8 character
tab stop, for all files, except for all Makefiles (plus rpm.mk).
The command `git diff -w` reports no changes.  There is no
functionality change in calc: only ASCII tabs to ASCII spaces.

Fixed trailblank.  It was pruning . in its find search.
Added check for ASCII tabs is non-Makefiles.... [read more](/p/calc/news/2024/07/calc-21510-release/)

The following are the changes in this release:

 Thanks to GitHub user @ashamedbit, a long standing memory leak in
 zrandom.c has been fixed.

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!

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)

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.... [read more](/p/calc/news/2023/12/calc-21502-release/)

Due to a missing verson.h file, this release was moved under old-calc.

We will release a version 2.15.0.1 soon.

Sorry (tm Canada 🇨🇦).

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.

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:... [read more](/p/calc/news/2023/08/calc-21430-release/)

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.... [read more](/p/calc/news/2023/07/calc-21420-release/)

The following are the changes in this release:

Fixed version numbers in two cases in CHANGES that referred
to the 2.14.2.x instead of 2.14.1.x.

Rename MINGW Makefile variable (a holdover from MINGW32_NT-5.0)
to OSNAME.

Fixed FUNCPTR typedef in hist.c to fix deprecated compiler warnings.

Fixed when USE_READLINE, READLINE_LIB, READLINE_EXTRAS, and
READLINE_INCLUDE are set to empty (disable use of the GNU-readline
facility).... [read more](/p/calc/news/2023/06/calc-21416-release/)

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).

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.... [read more](/p/calc/news/2022/11/calc-21412-release/)

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.

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

Release v2.14.0.13

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.... read more

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.... [read more](/p/calc/news/2021/12/calc-214012-release/)

The following are the changes in this release:

Identical to v2.14.0.7: now declared a stable release.

The following are the changes in this release:

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 usually ${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.... [read more](/p/calc/news/2021/04/calc-21301-release/)

Fixed typo (missing quotes) in the env rule.

Fixed intendation problem in CHANGES.

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.... [read more](/p/calc/news/2021/03/calc-21300-release/)

The following are the changes in this release:

Fixed a typo typo in help/Makefile that caused the build of

to all sub-directory Makefiles from the top level Makefile.
