Targus USB retractable calculator keypad
A The “Add Mode” automatically adds a
decimal point and two decimal places to all
values, even if you don’t input a decimal
point. This mode is very useful when
performing calculations in dollars or other
currencies that require two decimal places.
If you press the DEL key while entering a
value or you are performing an operation
other than addition and subtraction, the
calculator does not add decimal spaces.
