The following are the changes from calc version 2.12.6.6 to date:
The following are the changes from calc version 2.12.6.9 to date:
Fixed a number of core dump bugs related to the calculation of
tan(), cot(), sec(), csc(), tanh(), coth(), sech(), and csch(),
asin(), acos(), asinh(), acosh(), where when a call to an
underlying function produced an invalid value. Thanks goes to
github user wuxiuheng for reporting this problem.
A number of trigonometric and hyperbolic functions that incorrectly
returned E_LOGINF, now return a new error code that is more
specific to the trigonometric or hyperbolic function. The
following is a list of these new error codes: E_TAN3 E_TAN4
E_COT3 E_COT4 E_SEC3 E_CSC3 E_TANH3 E_TANH4 E_COTH3 E_COTH4
E_SECH3 E_CSCH3 E_ASIN3 E_ACOS3 E_ASINH3 E_ACOSH3 E_ATAN3 E_ACOT3
E_ASEC3 E_ACSC3 E_ATANH3 E_ACOTH3 E_ASECH3 E_ACSCH3.
Added regression tests 3729 thru 3732 to test E_TAN3, E_COT3,
E_SEC3 and E_CSC3 respectively.
The following are the changes from calc version 2.12.6.6 to 2.12.6.8:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
