Real base raised to real exponent
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)
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.
- See the SIRFUNC EXEC parameter for an explanation of when this high-performance, high-precision version of the IBM mathematical function from the Sirius Mods is used, as opposed to the version of the $function in the Model 204 FUND or FUNDLE CSECT.
Examples
$rxpr(9, 2) = 92 = 81 $rxpr(64, .5) = 8 $rxpr(256, .25) = 4
