Change zispowerof2() interaface to take a FULL ptr as the 2nd arg:
zispowerof2(ZVALUE z, FULL *log2).
Added qispowerof2(NUMBER *q, NUMBER **qlog2) to qfunc.c.
Change log2() builtin to use the new qispowerof2() internal interface.
Update LIBRARY to reflect the new zispowerof2() internal interface
and the new qispowerof2() internal interface.
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).
Fix "Under source code control" date for new version.h file.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
The sign in a ZVALUE is now of type SIGN, whcih is either
SB32 when CALC2_COMPAT is defined, or a bool.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
The constants:
9, 9/10, 10/9, 24, 360, 400
are used by func.c only, so there were moved
from {q,z}math.{c,h} to func.c.
The constants:
3, 4
are used by zrandom.c only, so there were moved
from {q,z}math.{c,h} to zrandom.c.
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.

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.
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!
