Only time I could think of was to have higher precision for Mandelbrot zooming generation, where IEE 64 bit runs out of steam at some point when zooming right in.
That is fairly intensive/interative though and I’m not sure you could get really high performance out of such extended precision integers ? > On 18 Aug 2022, at 4:34 pm, Elijah Stone <elro...@elronnd.net> wrote: > > Another strange question, this time to do with extended precision numbers. > > Have you ever wanted good performance out of a large array of > extended-precision integers (or, for that matter, rationals), where most of > the integers involved would not have fit in a machine integer (magnitude > approx. 2^63)? > > (I recognise that this is probably not an ideal place to ask, given that j's > extended integers have not historically been even remotely performant.
