### Exponentiate (x ^ y)

Basic and Crystal syntax.

##### Usage

`x ^ y`

Raise x to the power of y.

Note: The Number value y can be fractional, and it can be positive or negative. The Number value x can be fractional, but can be negative only if y is a whole number.

##### Examples

The following examples are applicable to both Crystal and Basic syntax:

`3 ^ 2`

Returns 9.

`3 ^ .5`

Returns 1.73205....

`(-3.5) ^ 2`

Returns 12.25. Note that the Exponentiation operator has a higher precedence than Negation, so -3.5 ^ 2 is different from (-3.5) ^ 2.

`3 ^ (-2)`

Returns .111...

Note: To express a number to a negative power, enclose the power in parentheses.
