$RxpI

Real base raised to integer exponent

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)

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 a 0 is returned.

For example:

$RXPI(2, 3) = 2&'sup(3) = 8 $RXPI(.5, 1.4) = $RXPI(.5, 1) = .5

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.
