Overloaded arithmetic operators for Localize.Unit.t() values.

When use Localize.Unit.Operators is added to a module, the +, -, *, and / operators are overridden so that they dispatch to Localize.Unit.Math when one or both operands is a %Localize.Unit{} struct. For all other types, the standard Elixir/Erlang operators are used.

The operators raise on error (they use the bang convention internally) so they can be used in natural arithmetic expressions.

Usage

defmodule MyApp.Physics do
  use Localize.Unit.Operators

  def kinetic_energy(mass, velocity) do
    # mass and velocity are Localize.Unit structs
    half = Localize.Unit.Math.mult(mass, 0.5) |> elem(1)
    half * velocity * velocity
  end
end
