Fractions

This is a sample project to implement fraction operations in Elixir and organize the code in a functional programming context. One of the things I'm struggling with is using a pattern to organize code and functions into layers and not expose a lot of the system where it's unnecessary.

Roadmap:

• Implement add/2 Return the result of the sum of a fraction by another.
• Implement add_integer/2 What happens when you add an integer to a fraction?
• Implement subtract/2 Return the result of the subtraction of a fraction by another.
• Implement multiply/2 Return the result of the multiplication of a fraction by another.
• Implement divide/2 Return the result of the division of a fraction by another.
• Implement equivalent/1 Returns the smallest equivalent fraction.
• Implement proper?/1 Returns true when it receives a proper fraction, that is, a fraction where the numerator is smaller than the denominator.
• Implement value/1 Converts the fraction value to a float.
• Implement print/1 Prints the fraction into a readable format, as a/b

Installation

If available in Hex, the package can be installed by adding fractions to your list of dependencies in mix.exs:

def deps do
  [
    {:fractions, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/fractions.
