How do I take the square root of a number in Elixir?


How do I take the square root of a number in Elixir? There doesn't seem to be a Math module or anything, and there is no function like sqrt().


Solution

  • Elixir compiles to BEAM, which makes it compatible with Erlang modules. As you said, :math.sqrt(x) is essentially running Erlang code.
