Is there any particular reason for

Random

to not have range-based float generation?

Mostly to keep API simple and not bloated with every possible overload. Basically, once you have

nextBits

you can implement every other method as extension on top of

nextBits

, but it can be ineffective and complicates delegation to platform-specific implementations. So only essential and common (for some definition of “essential” and “common” 🙂) API was introduced

But I mean... All the others were implemented

Most people don't need random floats in all fairness

I think it's also because floats are not evenly distributed across their possible values: You have more values between 0 and 1 than between max value and max value minus one, so it could be confusing to have less randomness because of an offset of the range.

Thanks all!
