Mathematical Calculations26
In RPN mode, the % key calculates x % of the number on Level 2 of the stack, when x is
the number on Level 1 of the stack. It does not modify the number on Level 2 of the stack, and
thus allows you to perform addition or subtraction after pressing
% to add or subtract x %
from the number.
For example,
200I25% returns 50, but 200 is still on Level
2 of the stack, and pressing
- returns 150, or 200-25%.
