Improve builtin function strings, as printed by help builtin,
that use an optional accuracy (epsilon) arg by adding a comma.
Added the following new trigonometric functions:
crd(x [,eps]) trigonometric chord of a unit circle
acrd(x [,eps]) inverse trigonometric chord of a unit circle
Added the following new trigonometric functions:
exsec(x [,eps]) exterior trigonometric secant
aexsec(x [,eps]) inverse exterior trigonometric secant
excsc(x [,eps]) exterior trigonometric cosecant
aexcsc(x [,eps]) inverse exterior trigonometric cosecant
Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Added to test 34dd, some if the missing inverse trigonometric tests.
The trigonometric file files have had several bug fixed.
The EXAMPLE sections of trigonometric file have
been made consistent.
Added these new help files in anticipation of
the code for these new (i.e., to be written) builtin functions:
hacovercos hacoversin havercos haversin
ahacovercos ahacoversin ahavercos ahaversin
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".
