WebBasically, you use them due to size and speed considerations. Bitwise operations are incredibly simple and thus usually faster than arithmetic operations. For example to get the green portion of an rgb value, the arithmetic approach is (rgb / 256) % 256. With bitwise operations you would do something as (rgb >> 8) & 0xFF. The latter is ... WebJan 31, 2024 · Efficient Approach: Use bit manipulation in order to find the quotient. The divisor and dividend can be written as . dividend = quotient * divisor + remainder. As every number can be represented in base 2(0 or 1), represent the quotient in binary form by using the shift operator as given below: Determine the most significant bit in the divisor.
