The numeric keypad located on the right side of your keyboard will serve as your
calculator. See the figures below to relate the display to the keys on the numeric
keypad that control it.
Note that the ANSI keyboard calculator display is identical to the ones shown below
for the PC keyboard except that the controlling keys on the numeric keypad are
different (the ANSI keyboard control keys include PF1-PF4 keys and function keys
F16-F20).
The calculator can process up to 10 digits to the left of the decimal point, and up to 9
to the right. When a number or number operator is pressed, it is momentarily
