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().

Also, since Elixir version 1.13, you can use exponent syntax.

x ** 0.5

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

Hah. Found it. You take the square root like this:

:math.sqrt(x)
