FizzBuzz in Elixir

fizzbuzz.exs

defmodule FizzBuzz do
  def convert_num(0, 0, _), do: "FizzBuzz"
  def convert_num(0, _, _), do: "Fizz"
  def convert_num(_, 0, _), do: "Buzz"
  def convert_num(_, _, n), do: n

  def fizz_buzz(n) do
    convert_num rem(n, 3), rem(n, 5), n
  end

  def fizzify(range) do
    Enum.map range, &(fizz_buzz(&1))
  end
end

IO.inspect FizzBuzz.fizzify(1..20)

There's probably a better way to do this, but it's my first bit of Elixir so just happy it works 😄
