In computing, the least significant bit is the bit position in a binary integer giving the units value, that is, determining whether the number is even or odd. The lsb is sometimes referred to as the right-most bit, due to the convention in positional notation of writing less significant digits further to the right. It is analogous to the least significant digit of a decimal integer, which is the digit in the ones position. It is common to assign each bit a position number, ranging from zero to N-1, where N is the number of bits in the binary representation used. Normally, this is simply the exponent for the corresponding bit weight in base-2. Although a few CPU manufacturers assign bit numbers the opposite way, the term lsb remains unambiguous as an alias for the unit bit. By extension, the least significant bits are the bits of the number closest to, and including, the lsb. The least significant bits have the useful property of changing rapidly if the number changes even slightly. For example, if 1 is added to 3, the result will be 4 and three of the least significant bits will change. By contrast, the three most significant bits stay unchanged.
