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
