WebBit shifting is the act of shifting a set of bits to the left or the right. To shift bits to the left, use <<. Additional bits, 0 s, will be added on the right-hand side. 0b1001 << 2 = 100100 To shift bits the other way, use >>. This will discard the right-hand bits. Note that this operation retains the first bit for signed integers. WebLSR – logical shift by n bits – unsigned division by 2n ! ASR – arithmetic shift by n bits – signed division by 2n!
