WebMar 21, 2024 · 2’s complement has this nice property that first bit is a sign bit because all positive starts with 0 whereas all negative with 1. 5) Memory overflow check: While doing addition, we made sure that our answer is within the range but while designing hardware, memory overflow needs to be detected. 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 ...
