WebJan 24, 2024 · The bitwise left shift (<<) operator shifts bits to the left. 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. WebA bit rotation of a w -bit word by r bits to the right transforms a w -bit word X = ( x w − 1, x w − 2, …, x 1, x 0) into the w -bit word ROTR ( X, r) = ( x r + w − 1 mod w, x r + w − 2 mod …

The bit shifts are sometimes considered bitwise operations, because they treat a value as a series of bits rather than as a numerical quantity. In these operations, the digits are moved, or shifted, to the left or right.
