WebThe terms machine epsilon, machine precision, and unit roundoff aren’t used consistently across references, but the differences are minor for our purposes. 2 Actually, there are some still-smaller denormalized numbers that have less precision, but we won’t use that level of detail. Introduction Problems and conditioning WebA floating-point system can be used to represent, with a fixed number of digits, numbers of very different orders of magnitude — such as the number of meters between galaxies or between protons in an atom. For this reason, floating-point arithmetic is often used to allow very small and very large real numbers that require fast processing times.
