My Lua rewrite of the NVal and NVal list templates is complete enough to share. I achieved a speed improvement of over 5x vs. my copy of the current code (pre Gen. Fermat) on my personal server. This...

I concur on the RPN order, and as someone who's dabbled a bit in Lisp-style languages, prefix/Polish notation is superior to infix as well, at least in CS. (Try getting the uninitiated to switch to...

It doesn't have to be a particularly noteworthy factor for Stargate to be fond of it. (Re-read the thread title.) Now, if we start adding sub-64-bit factors here, that may be crossing the line.

I would have guessed the opposite. On bad hardware, Gerbicz should catch more errors than Jacobi (key word is catch; the actual number of bad iterations should be roughly equal either way), but also...

I don't think a double (53-bit mantissa) is enough precision for that number, and even a long double on x86 (which I believe gives you the 80-bit x87 extended-precision float, with a 64-bit mantissa)...

AFAIK gwnum and Prime95/mprime have the same license. I don't see a license file in the gwnum source folder, but both LLR and OpenPFGW (which both link gwnum) reference similar terms.
