Fixed SEE ALSO typo in help randperm.
Added the following new trigonometric functions:
haversin(x [,eps]) half versed trigonometric sine
hacoversin(x [,eps]) half coversed trigonometric sine
havercos(x [,eps]) half versed trigonometric cosine
hacovercos(x [,eps]) half coversed trigonometric cosine
ahaversin(x [,eps]) inverse half versed trigonometric sine
ahacoversin(x [,eps]) inverse half coversed trigonometric sine
ahavercos(x [,eps]) inverse half versed trigonometric cosine
ahacovercos(x [,eps]) inverse half coversed trigonometric cosine
Fixed calc regression test 42dd to set the display value back to 20.
Added test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Fix and improve recently comments and variable names added new
trigonometric functions in comfunc.c, func.c, qtrans.c.
Rename E_BROUND to E_BROUND_1 as per an earlier change
on the E_STRING formats.
E_BROUND ==> E_BROUND_1
Improve the ciarify of calc regression suite (regress.cal) to mostly
use E_STRING errsym instead of numeric errnum values for error()
and errno() related tests.
Added tests to the calc regression test suite (cal/regress.cal) to
verify that the errnum calc computation error codes and their
E_STRING values have not changed.
NOTE: errstr was renamed to errsym.
Added errsym builtin function. The errsym(errnum | "E_STRING")
builtin, , when given a valid integer errnum that corresponds to a
calc error condition, will return an E_STRING string, AND when given
a valid E_STRING string that is associated with a calc error
condition, will return errnum integer that corresponds to a calc
error condition.
Supplying a non-integer numeric errnum code to error(), errno(),
strerror(), or errsym() will result in an error.
When errtbl.c is being compiled for the errcode executable,
(when ERRCODE_SRC is defined), skip functions that make
called to math_error() and name_newerrorstr() from libcalc.
Now the "E_STRING" errsym strings in error_table[], with exception
to the 1st E__BASE entry, all other errsym strings must match the
following regular expression:
^E_[A-Z][A-Z0-9_]+$
Renamed "E_1OVER0" to "E_DIVBYZERO".
Renamed "E_0OVER0" to "E_ZERODIVZERO".
Removed from errsym.h (as built by errcode -d via the Makefile),
E__NONE, E__BASE, E__USERDEF, and E__USERMAX. These symbols were
also defined in errtbl.h, which is NOW the place of the #define.
Update .gitigore with another temporary file.
Rename the #define E__COUNT to ECOUNT to avoid confusion
with "E_STRING" error symbols.
Improve formatting of help/error, help/errno, and help/strerror.
Update .gitignore.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Changed #define E_USERDEF to #define E__USERDEF.
Removed use of E_USERDEF, E__BASE, E__COUNT, and E__HIGHEST
from custom/c_sysinfo because the c_sysinfo is just a demo
and this will simplify the custom/Makefile.
The include file calcerr.h is now the errsym.h include file.
The calcerr.tbl has been replaced by errtbl.c and errtbl.h.
The calcerr_c.awk, calcerr_c.sed, calcerr_h.awk, and
calcerr_h.sed files are now obsolete and have been removed.
The calcerr.c and calcerr.h now obsolete and are no longer built.
The calc computation error codes, symbols and messages are now in
a error_table[] array of struct errtbl.
An E_STRING is a string corresponds to an error code #define.
For example, the E_STRING for the calc error E_STRCAT,
is the string "E_STRING". An E_STRING must now match
the regular expression: "^E_[A-Z0-9_]+$".
The old array error_table[] of error message strings has been
replaced by a new error_table[] array of struct errtbl. The struct
errtbl array holds calc errnum error codes, the related E_STRING
symbol as a string, and the original related error message.
To add new computation error codes, add them near the bottom of the
error_table[] array, just before the NULL entry.
The ./errcode utility, when run, will verify the consistency of
the error_table[] array.
The Makefile uses ./errcode -e to generate the contents of
help/errorcodes file. The help errorcodes now prints
information from the new cstruct errtbl error_table[] array.
The help/errorcodes.hdr and help/errorcodes.sed files are
now obsolete and have been removed.
The Makefile uses ./errcode -d to generate the contents of the
errsym.h include file.
Updated .gitignore and trailblank to support the above changes.
