Unit in the last place Unit in the last place In computer science and numerical analysis, unit in the last place or unit of least precision (ULP) is the spacing between floating-point numbers, i.e., the value the least significant digit represents if it is 1. It is used as a measure of accuracy in numeric calculations. In radix "b", if "x" has exponent "E", then ULP("x") = machine epsilon · "b", but alternative definitions exist in the numerics and computing literature for "ULP", "exponent" and "machine epsilon", and they may give different equalities. Another definition, suggested by John Harrison, is slightly different: ULP("x") is the
