Title: Varying length floating point arithmetic: a necessary tool
for the numerical analyst
Author: Tienari, Martti
Date: April 1967
Abstract: The traditional floating point arithmetic of scientific
computers is biased towards fast and easy production of
numerical results without enough provision to enable the
programmer to control and solve problems connected with
numerical accuracy and cumulative round-off errors. The
author suggests the varying length floating point arithmetic
as a general purpose solution for most of these problems.
Some general philosophies are outlined for applications of
this feature in numerical analysis. The idea is analyzed
further discussing hardware and software implementations.
