tan |
Function (ROM Call 0xFB*) |
Floating point tangent.
tan returns the tangent of floating point argument x, which is assumed
to be specified in radians.
Note: tan will return UNSIGNED_INF for all arguments
for which the tangent is infinity. Also, it will return NAN if the
argument is so big that reducing to the main period can't be performed without
complete losing of significant digits (i.e. when the magnitude of x is
greater than 1e13).
