I have implemented a mandelbrot-explorer in OpenGL. For deeper zooms I'm trying to implement double-double-arithmetic. I have working code for that in ...

I'm playing around with a PPC64 virtual machine emulated in qemu, trying to mimic a POWER8 CPU. Here, the long double type is different from the 80-b ...

One way of increasing precision beyond that of a double (e.g. if my application is doing something space-related that needs to represent accurate posi ...

There exist workloads for which double precision floating point is not quite adequate, hence a need for quad precision. This is rarely supplied in har ...

I've seen in wikipedia that someway to implement quad-precision is to use double-double arithmetic even if it's not exactly the same precision in term ...

When I first got a Haswell processor I tried implementing FMA to determine the Mandelbrot set. The main algorithm is this: This determines if n pix ...

If one were to emulate double precision floating point with two single precision floating points what would the performance be like, and can it be don ...

Context: double-double arithmetic “Double-double” is a representation of numbers as the sum of two double-precision numbers without overlap in the si ...

Following papers and source code for double-double arithmetic for some time, I still can't find out how exactly a dd_real ( defined as struct dd_real ...

I am writing a program for an embedded hardware that only supports 32-bit single-precision floating-point arithmetic. The algorithm I am implementing, ...
