The purpose of XPON is to calculate integer powers of
positive integers with more than the usual seven digits of pre
cision in FOCAL. As the result is computed, it is divided into
groups of five digits. Each group occupies a FOCAL variable.
The method of exponentiation is repeated multiplication.
Restrictions:  The base and the exponent must
both be integers

Source Language:  FOCAL
