Landon Curt Noll	42129a3672	change error printing from errnum to errsym ... When printing an error, calc used to print the errnum (error number): ; 1/0 Error 10001 Calc now prints the errsym (errsym): ; 1/0 Error E_DIVBYZERO Added errsym E_LN_3 for ln(0). Added errsym E_LOG_5 for log(0). Added errsym E_LOG2_4 for log2(0). Added errsym E_LOGN_6 for logn(0,base).	2023-10-03 22:12:14 -07:00

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	2023-10-02 22:43:33 -07:00
Landon Curt Noll	c78a893862	add exterior trigonometric functions ... 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.	2023-10-01 23:12:21 -07:00
