Real base raised to integer exponent
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $RxpI function.
The $RxpI function returns the value of its first argument raised to the power of its second argument. The second argument is initially rounded to the nearest integral value.
Syntax
%num = $RxpI(x, y)
Usage notes
- Omitted arguments are set to 0.
- If x equals 0, and |y| is less than or equal to 0, an error message is printed and the request is cancelled.
- If the result exceeds 7.237 x 1075, an arithmetic overflow occurs, and $RxpI returns the value 0.
Examples
$rxpi(2, 3) = 23 = 8 $rxpi(.5, 1.4) = $rxpi(.5, 1) = .5
