Constant function
The constant function can be used to store temporarily a
value that is added, subtracted, multiplied, or divided
constantly.
To use a constant, enter the value you want to use as
a constant and tap on an operator symbol twice. The
letter K is displayed in the calculation line when the
constant value has been stored. Enter a new value and
tap on the equals symbol (=) to perform the
calculation.
For example: Enter the value 2 in the calculator. Tap
twice on the plus symbol (+). The constant value 2 is
saved. Enter the value 5 and tap on the equals symbol
(=). The sum (7) is displayed. Enter the value 10.2 and
tap =. The sum (12.2) is displayed.
