I did a port of the Mersienne Twister (C-language edition) by Takuji
Nishimura and Makoto Matsumoto into D. It is a free function version and
doesn't use any classes. It also has a template for ranged random numbers.
eg..
uint v = genrand_range!(uint)(1, 10));
double f = genrand_range!(double)(-0.5, 0.5))
It can be found at

To get the object file only, compile with
dmd -c mt
to get a stand alone self-test version compile with
dmd -version=main mt

Did you get this from Torus Trooper? If not then that's highly coincidental. -- -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCS/MU/S d-pu s:+ a-->? C++++$ UL+++ P--- L+++ !E W-- N++ o?

I got it from Makoto's RNG site ... http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/MT2002/emt19937ar.html -- Derek Parnell Melbourne, Australia

Hey... I've already implement it in 'helix' on dsource. It is in svn. I'll test your implementation on weekend to see which is faster :) -- Victor (aka nail) Nakoryakov nail-mail<at>mail<dot>ru Krasnoznamensk, Moscow, Russia

Knock yourself out ;-) I haven't bothered tuning it, just made it more D-like. -- Derek Parnell Melbourne, Australia

Attached is my D port of MT19937. I sent it to Walter last April as a proposed replacement for std.random.
