Higher Quality Random Floats

You think there might be applications like complex very large simulations where an event with probability 1:10^38 matters?

You are aware that the current age of the universe is < 10^27 nanoseconds, just for comparison?

But what if you want a random number between two very small floats?

Fair enough, if a user asks for a random float between [0, 1e-38f] then subnormals are expected.

I was just thinking about the (0,1) case, under the mistaken assumption that one could map it to (a,b) via multiplication/addition, but you're right -- if you want (a,b) perfectly () then it's not obvious to me.

() up to inaccuracies of cosmologically negligible scale
