Real base raised to real exponent

**Note:** Many $functions have been deprecated in favor of Object Oriented
methods. There is currently no direct OO equivalent for the `$RxpR` function.

The `$RxpR` function returns the value of its first argument raised to the power of its second argument.

## Syntax

%num = $RxpR(x, y)

## Usage notes

- If either of the following is true,
an error message is printed and a 0 is returned:
*x*is less than zero.*x*equals 0, and*y*is less than or equal to 0.

- If the result of the
`$RxpR`call exceeds 7.237 x 10^{75}, then an arithmetic overflow occurs, and`$RxpR`returns the value 0.

## Examples

$rxpr(9, 2) = 9^{2} = 81
$rxpr(64, .5) = 8
$rxpr(256, .25) = 4
