Exact and Approximated Error of the FMA
Abstract—The fused multiply accumulate-add (FMA) instruction, specified by the IEEE 754-2008 Standard for Floating-Point Arithmetic, eases some calculations, and is already avai...

Exact real arithmetic using centred intervals and bounded error terms
Approximations based on dyadic centred intervals are investigated as a means for implementing exact real arithmetic. It is shown that the field operations can be implemented on th...

On Taylor/Eddy solutions of approximate deconvolution models of turbulence
This article shows that, so called, general Green-Taylor solutions, also called Taylor solutions or eddy solutions of the 2d Navier Stokes equations are also exact solutions to app...

Pixel Approximation Errors in Common Watershed Algorithms
Abstract. The exact, subpixel watershed algorithm delivers very accurate watershed boundaries based on a spline interpolation, but is slow and only works in 2D. On the other hand, ...

Exact and error-bounded approximate color buffer compression and decompression
In this paper, we first present a survey of existing color buffer compression algorithms. After that, we introduce a new scheme based on an exactly reversible color transform, si...
