WebJan 24, 2024 · Bits that are shifted off the end of the binary number are lost forever. The bitwise right shift (>>) operator shifts bits to the right. 1100 >> 1 is 0110. 1100 >> 2 is 0011. 1100 >> 3 is 0001. Note that in the third case we shifted a bit off the right end of the number, so it is lost.

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.
