Integer 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 $IxPI function.
The $IxPI function returns the value of its first argument (rounded to the nearest integral value) raised to the power of its second argument (rounded to the nearest integral value). If |x| equals 0, and |y| is less than or equal to 0, an error message is printed and a 0 is returned.
Syntax
%num = $IxPI(x)
For example:
$IXPI(8,2) = 8&'sup(2) = 64 $IXPI(2.4,.5) = $IXPI(2,1) = 2
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.
