Bitwise AND a & b Returns a one in each bit position for which the corresponding bits of both operands are ones. Bitwise OR a | b Returns a one in each bit position for which the corresponding bits of either or both operands are ones. Bitwise XOR a ^ b Returns a one in each bit position for which the corresponding bits of either but not both operands are ones. Bitwise NOT ~ a Inverts the bits of its operand. Left shift a << b Shifts a in binary representation b (< 32) bits to the left, shifting in zeroes from the right. Sign-propagating right shift a >> b Shifts a in binary representation b (< 32) bits to the right, discarding bits shifted off. Zero-fill right shift a >>> b Shifts a in binary representation b (< 32) bits to the right, discarding bits shifted off, and shifting in zeroes from the left.
