Well, actually N provides the upper bound for the random number because everything is (mod N) ;)

Yeah, sorry :D Actually, I just realised I typed up the wrong equation...

What I meant to say is that I multiply rand by floor(rand/N2) and then take mod N of that result.

I don't know why I said N2 provided an upper bound ...

I think you should change it to be n^2. That way your users can scratch their heads trying to figure out how to get Rand mod 2 with integers...
