WebSHIFT_RIGHT shifts the bits of its argument ARG right by COUNT bits. The SHIFT_LEFT functions work the same for both UNSIGNED and SIGNED values of ARG, shifting in zero bits as necessary. The SHIFT_RIGHT functions treat UNSIGNED and SIGNED values differently. If ARG is an UNSIGNED number, vacated bits are filled with zeros WebJan 24, 2024 · The left operand is the expression to shift the bits of, and the right operand is an integer number of bits to shift left by. So when we say x << 1, we are saying “shift the bits in the variable x left by 1 place”. New bits shifted in from the right side receive the value 0. 0011 << 1 is 0110 0011 << 2 is 1100 0011 << 3 is 1000
