Description | simple versions: Yi = tan ( Xi )
expanded versions: Yi = C * tan( A*Xi+B )
For large values of Xi, round-off error becomes appreciable; if the Xi values are representable as rational multiples of p, it is better to use VF_tanrpi than VF_tan. |
|
Error handling | SING and OVERFLOW errors (for arguments very close to p/2) lead to a default result of ±HUGE_VAL. Precision errors lead to a default result of 0.0. |
|
Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
