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.

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).
Fix cases of spaces before tabs in Makefile and Makefile.simple.
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
correct internal function name of str2q().
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.

correct internal function name of str2z().

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!
