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). WebThe bit is the most basic unit of information in computing and digital communications. 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 + / − ...
