The name is a portmanteau of binary digit. [1] The bit represents a logical state with one of two possible values. These values are most commonly represented as either "1" or "0", but other representations such as true / false, yes / no, on / off, or + / − ...

WebDec 17, 2015 · Generally you would count bits in an unsigned integer. The reason being that you're usually checking for bits set in a register or a mask, for example. Signed integers are represented using twos-compliment and I can't think why you'd want to count set bits in a signed integer (would be interested why if you definitely do want this). WebThis is known as the 'Hamming Weight', 'popcount' or 'sideways addition'. Some CPUs have a single built-in instruction to do it and others have parallel instructions which act on bit vectors. Instructions like x86's popcnt (on CPUs where it's supported) will almost certainly be fastest for a single integer. Some other architectures may have a slow instruction …
