# DESCRIPTION

This module exports the missing inverse and hyperbolic trigonometric functions of real numbers. The inverse functions return values cooresponding to the principal values. Specifying an argument outside of the domain of the function where an illegal divion by zero would occur will cause infinity to be returned. Infinity is Perl's version of this.

This module is a sub-class of Math::Trig::Units and operates in gradians. For full documentation see the Math::Trig::Units module.
