In computer science, Unit in the Last Place or Unit of Least Precision (ULP) is the gap between two very close floating-point numbers. To be exact, ulp(x) is the gap between the two floating-point numbers closest to the value x. The amount of error in the evaluation of a floating-point operation is often expressed in ULP. An average error of 1 ULP is often seen as a tolerable error.
