WebApr 1, 2013 · The shift operators shift the left operand by the shift count specified by the right operand. They implement arithmetic shifts if the left operand is a signed integer and logical shifts if it is an unsigned integer. The shift count must be an unsigned integer. There is no upper limit on the shift count. WebFeb 2, 2024 · A bit shift is an operation where a succession of bits is moved either to the left or the right. For logical bit shifts, the bits shifted out of the binary number's scope are lost, and 0's are shifted in on the other end. This differentiates this method from the circular and arithmetic bit shift.
