Possible Double Rounding in Division Algorithms

This section deals with floating point \(a,b\) values, not necessarily between 1 and 2. Assume they are non-negative, though. For this,...

Using The Newton Iteration For Correctly Rounded Division With FMA

We need to calculate \(o(a/b)\) where \(a,b\) are binary floating point numbers, and \(o\) is RN, RD, RU or RZ. We have a useful proof:...

Variants of the Newton Raphson Iteration

Assume \(\beta=2\) for this section. Some of it may not work for decimal. We want to approximate \(b/a\). Assume \(1\le a,b<2\). In...

Computation of Residuals of Division and Square Root With an FMA

For this article, define a representable pair for a floating point number \(x\) to be any pair \((M,e)\) such that...
