Implementation and Evaluation of Interval Arithmetic Software. Report 2. The Honeywell MULTICS System.

Abstract

This is Report 2 of a series entitled Implementation and Evaluation of Interval Arithmetic Software. Interval arithmetic can be used to determine the precision of the arithmetic required to guarantee a given precision in the results of an algorithm. In general, whether using interval or regular arithmetic, the greater the precision the longer the run time required for a given algorithm. A 56 decimal digit version of the original MULTICS interval package was implemented on the MULTICS system. It is concluded that the use of single precision and 56 decimal digit extended precision interval arithmetic can, at times, be extremely useful. The testing showed that, when using the 56 decimal digit data type, much better bounds were obtained for the results than when using the single precision interval data type.
