Rounding

Abstract

The objective of floating-point rounding is the approximation of a real number by one that is representable in a given floating-point format. Thus, a rounding mode is a function that computes an n-exact value \(\mathcal {R}(x,n)\), given a real number x and precision n. In this chapter, we investigate the properties of a variety of rounding modes, including those that are prescribed by the IEEE standard as well as others that are commonly used in implementations of floating-point operations.
