Base-n Calculations (BASE-N)
Press N4(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:
w(DEC) for decimal, 6(HEX) for hexadecimal, l(BIN) for binary, or
i(OCT) for octal.
To enter the BASE-N Mode, switch to the binary mode, and
calculate 11
