Base-n Calculations (BASE-N)

Press (BASE-N) to enter the BASE-N Mode when you want to

perform calculations using decimal, hexadecimal, binary, and/or octal

values. The initial default number mode when you enter the BASE-N Mode

is decimal, which means input and calculation results use the decimal

number format. Press one of the following keys to switch number modes:

7(DEC) for decimal, (HEX) for hexadecimal, 5(BIN) for binary, or

2(OCT) for octal.

To enter the BASE-N Mode, switch to the binary mode, and
