For calculating the power, the number is multiplied by itself for the
number of times expressed by the power.
An example is:
rexx -e N=1.01; P=8; R=1;
I thought that we already beat this one to death.
If you preface your expression with NUMERIC DIGITS 20 you will see that the
answers are the same. After each math operation rounding is performed. So in
repeated multiplication rounding is performed P times, while in the case of the
power
