perform add-on, discount or division percentage calculations. You
may also perform percentage calculations with dimensional units
(feet, inch, etc.), in any format (linear, square or cubic).

5 0 0 f x 1 8 % 90 FEET 0 INCH
Add 10% to 137 square feet:
1 3 7 f f + 1 0 % 150.7 SQ FEET
Subtract 20% from 552 feet 6 inches:
5 5 2 f 6 i – 2 0 % 442 FEET 0 INCH
Divide 350 cubic yards by 80%:
3 5 0 y y y ÷ 8 0 % 437.5 CU YD
