# = Trigonometric and transcendental functions for complex numbers.
#
# CMath is a library that provides trigonometric and transcendental
# functions for complex numbers. The functions in this module accept
# integers, floating-point numbers or complex numbers as arguments.
#
# Note that the selection of functions is similar, but not identical,
# to that in module math. The reason for having two modules is that
# some users aren't interested in complex numbers, and perhaps don't
# even know what they are. They would rather have Math.sqrt(-1) raise
# an exception than return a complex number.
#
# For more information you can see Complex class.
#
# == Usage
#
# To start using this library, simply require cmath library:
#
#   require "cmath"

module CMath

include Math

# Backup of Math is needed because mathn.rb replaces Math with CMath.
