Abstract
We propose the round-off error estimation using IEEE754 floating-point arithmetic which widely used on various workstations and personal computers. Interval Analysis is one of the standard methods in order to estimatite round-off errors in numerical processes, but it is not more convenient for a lot of users. In this paper, we explain the proposed estimation and show the source programs which can run on SparcStaion, PC-9801 and IBM PC/AT compatible. Finally, numerical experiments demonstrate the effectiveness of the proposed estimation.
