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".
Moved versin() and coversin() to bottom of functions in func.c
(however the builtin function list remains sorted).
Created a historical trig functions section for cmath.h and qmath.h.
Moved cal/test3500.cal to cal/test9300.cal to make room
for future trip tests going from test 3427 thru 3599.
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).
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").
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.
While 0^0 == 1, now for y > 0, 0^y == 0.
Adjusted cal/test8900.cal to reflect the this bug fix.
Added tests to cal/regress.cal to help verify bug fix is fixed.
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.
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:

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:

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.
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.
Fixed how the *.tar.bz2 are formed. The calc-2.12.8.0.tar.bz2 file
that was formed for calc version 2.12.8.0 was missing most files.
Expanded 'make chk' to also verify that 'make distchk' and 'make
distlist' execute successfully. This will help check a regression
of the bug that produced the bogus calc-2.12.8.0.tar.bz2 file.
Added additional regression tests related 0^(zero_expression)==1.
This code %g is preliminary.
Fixed some code style issues to match the current code style.
Added regression tests and help file updates to printf and strprintf.
Fixed use of magic number -4: using -P instead.
Noted two problem areas with XXX comments in qio.c:
1) need a qprintfg function
2) re-write to not modify conf->outdigits
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!
