Rational

Elixir library for working with rational numbers.

iex> ra = Rational.new(4,3)
%Rational{4/3}

iex> rb = Rational.sub ra, Rational.new(2,3)
%Rational{2/3}

iex> Rational.approx rb
0.6666666666666666

iex> Rational.mul rb, Rational.new(4,9)
%Rational{8/27}

Implements:

• add, sub, mul, div
• approx
• pow
• gcd
