Defines many trigonometric functions not defined by the
core Perl, plus the constant pi
and
some additional functions for converting angles. For example:
use Math::Trig; $x = tan(0.9); $halfpi = pi/2;
The following functions are defined. A slash (/
) between two functions means the values
are aliases.
