Real base raised to real exponent
Note: Most Sirius $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 1075, then an arithmetic overflow occurs, and $RxpR returns the value 0.
Examples
$rxpr(9, 2) = 92 = 81 $rxpr(64, .5) = 8 $rxpr(256, .25) = 4
