The keys in this menu perform operations on binary integers. Note that both logical and arithmetic right-shifts are provided. INV LSH rotates one bit to the left.

The "difference" function (normally on b d) is on INV AND. The "clip" function (normally on b c) is on INV NOT.

The DEC, HEX, OCT, and BIN keys select the current radix for display and entry of numbers: Decimal, hexadecimal, octal, or binary. The six letter keys A through F are used for entering hexadecimal numbers.

The WSIZ key displays the current word size for binary operations and allows you to enter a new word size. You can respond to the prompt using either the keyboard or the digits and ENTER from the keypad. The initial word size is 32 bits.
