Now, that you mention it... `JDKRandom` of Commons RNG provides negative and positive values. However, there's still functionality missing to create values in between a specified range.

Now, that you mention it... `JDKRandom` of Commons RNG provides negative and positive values. Imo it still makes a lot of sense to add a link to the Commons Lang Javadoc.

> `RandomUtils` only allows to generate random numbers of different numeric types (`byte`, `short`, `double`, etc.) within the range 0 (inclusive) and the maximum value of the respective type. It'd be nice if there were methods to create random numbers for the range between the minimal and the maximal value for all numeric types.
> I'm aware of workarounds like https://stackoverflow.com/questions/27976857/how-to-get-random-number-with-negative-number-in-range, but they're not tested and require quite some thinking which can be avoided (which is afaik one of the many motivations for the Apache commons libraries).
> If such methods already exist they should be definitely linked in the Javadoc of `RandomUtils`.
