Abstract

In general, the basic arithmetic operations on digital computers are not exact but are subject to rounding or truncation errors. This article is concerned with the cumulative effect of these errors. It will be assumed that the reader has read the article on MATRIX COMPUTATIONS, since the results will be illustrated by examples from that area.
