pow(base, exponent)
Specs
Raises base to the power of exponent.
Since :math.pow/2 always does floating point arithmetic, whereas
PassiveSupport.Integer.exponential/2 will do arbitrary precision arithmetic
if the exponent is a positive integer, Math.pow/2 checks the types of
base and exponent and delegates out to the appropriate function based on
what it finds.
Examples
iex> pow(2, 5)
32
iex> pow(2, 5.0)
32.0
iex> pow(2, 200)
