WebJun 28, 2011 · Many of us have used bit shifts for arithmetic that is simple on pencil and paper, but not available on our CPUs. For example: I've used bit shifts for projects involving factoring large composites into their prime factors. I have also used bit shifts for finding the square and cube root of arbitrarily large integers. Webbecause negative number is stored in 2's complement form in the memory. consider integer takes 16 bit. therefore -1 = 1111 1111 1111 1111. so right shifting any number of bit would give same result. as 1 will be inserted in the begining.

WebFeb 19, 2024 · The SHL and SHR operators work not on arrays, but on individual registers, e.g. SHL (3, 1) will result in 6 ( 0000 0011 -> 0000 0110 ). However If you shift a number beyond it's holding capacity, the bits that go past the boundary are completely lost, i.e. they do NOT overflow into the next memory register! – Guiorgy.
