Table A.2.6 Bitwise operators. x and y are integers. If mixed integer types, the

result will be of the wider type.

Operator Name Description

Flip each bit, ones to zeros, zeros to ones.

~x Compliment

AND each bit a with corresponding bit in b.

x&y AND

x | y

OR each bit in a with corresponding bit in b.

OR

x ^ y

XOR each bit in x with corresponding bit in y.

XOR

x << y

Shift x to the left by y bits. High-order bits
lost.
Zero bits fill in right bits.

Shift left

Shift x to the right by y bits. Low-order bits
lost.
Same bit value as sign (0 for positive
numbers, 1 for negative) fills in the left
bits.

x >> y Shift right

-
Signed

Shift x to the right by y bits. Low-order bits
lost.
Zeros fill in left bits regardless of sign.

x >>> y Shift right

-
Unsigned
