Rational

Implements exact rational numbers. In its simplest form, Rational.new(3,4) will produce an exact rational number representation for 3/4. Both parameters must be integers. The numerator defaults to 0 and the denominator defaults to 1 so that Rational.new(3) = 3/1 = 3 and Rational.new() = 0/1 = 0

Installation

Add rational as a dependency in your mix.exs file.

def deps do
  [ { :rational, "~> 0.0.0" } ]
end

After you are done, run mix deps.get in your shell to fetch and compile the Rational module. Start an interactive Elixir shell with iex -S mix and try the examples in the examples section.

Documentation

Documentation for the package is available online via Hex at http://hexdocs.pm/rational. You can also generate local docs via the mix task

mix docs

This will generate the HTML documentation and place it into the doc subdirectory.

Examples

iex> Rational.new(3, 4)
%Rational{den: 4, num: 3}

iex> Rational.new(8,12)
%Rational{den: 3, num: 2}
