Cross Platform Rnd() Consistency

Monkey Forums/Monkey Programming/Cross Platform Rnd() Consistency

I'm guessing probably not but... Is it possible to create a random generator that behaves exactly the same over many platforms?

Yes. Monkey's Rnd should be one. If you're seeing inconsistencies with the standard Monkey one then I'd guess it's due to double/float differences. What problems are you seeing?

Oh wow... you can probably ignore me, I could've sworn they generated different figures, but they don't! Oops.

mmm... that's interesting and quite useful.

really? I wrote my own random number module for this purpose. oh well ;-)

I only checked XNA and HTML5 at this time, but ignoring precision (which is fine for me), they generate the same numbers

I have an integer rand() in the code section that clones the version from MSVC.
