I get it. It can be used for things like stochastic sampling.

However, it doesn't provide support for e.g. 1/100 or 1/500.

So here's a suggestion:

Instead of "value" (which is irrelevant) & "mask" (which is what really controls the probability), wouldn't it be better if "value" was an inverse probability (and "mask" was irrelevant)? E.g. value=500 means that there is a 1 of 500 probability of a match.

Would this kind of random item better serve the purpose?

Or is the random item, in its current form, also required for other purposes?
