 Returns the value of a base (first argument) raised to the power of an exponent (second argument).
-Both arguments must be numeric.
+Both arguments must be numeric. The output is always a double.

-==== Type rules
-
-The type of the returned value is determined by the types of the base and exponent.
-The following rules are applied to determine the result type:
-
-* If either of the base or exponent are of a floating point type, the result will be a double
-* Otherwise, if either the base or the exponent are 64-bit (long or unsigned long), the result will be a long
-* Otherwise, the result will be a 32-bit integer (this covers all other numeric types, including int, short and byte)
-
-For example, using simple integers as arguments will lead to an integer result:

-NOTE: The actual power function is performed using double precision values for all cases.
-This means that for very large non-floating point values there is a small chance that the
-operation can lead to slightly different answers than expected.
-However, a more likely outcome of very large non-floating point values is numerical overflow.
