WebRight Shift. The bitwise right shift operator ( >>) is analogous to the left one, but instead of moving bits to the left, it pushes them to the right by the specified number of places. The rightmost bits always get dropped: Every time you shift a bit to the right by one position, you halve its underlying value. WebMost of the bitwise operators are binary, which means that they expect two operands to work with, typically referred to as the left operand and the right operand. Bitwise NOT ( …
