-- This package contains the generic functions which are instantiated with
-- predefined integer and real types to generate the runtime exponentiation
-- functions called by expanded code generated by Expand_Op_Expon. This
-- version of the package contains routines that are compiled with overflow
40 -- checks suppressed, so they are called for exponentiation operations which
-- do not require overflow checking
