WebJun 4, 2024 · Logical shift right simply inserts a 0 in the sign bit even if it was a negative number and shifts the entire bits to the right. While the Arithmetic shift keeps the sign bit and shifts the bits starting from the one that follows the sign bit. Logical shift right is represented by >>> while arithmetic shift right is represented by >> 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 ... fizer injection effectiveness
