In
computing, the
least significant bit (
LSB) 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 (right-most) position.
