Does anyone know how to generate a random number?

I would like a uniformly distributed random number between 0 and 1. Does Arc provide this?

I like to use the Mersenne Twister for my pseudorandom numbers. The source code (in C) is illuminating. Or you can check out www.netlib.org for other implementations (in e.g., Fortran 77). Should be straightforward to translate them.

It's in ruby too. Something that works nice if you're writing models using the gillespie algorithm (as I happen to be ;).
