What about other ways of generating a random number, like just random:uniform() without the limit? If we're looking at just a random number generator, there are a lot of ways to go about that that don't specify the range the number must be in. For example, there's also Erlang's rand module, which uses a different algorithm than random but isn't truly random enough for stuff like cryptography, but might be random enough for most other uses.

What I needed was to generate a random number among a range. I should've explicitly explained that in the description.
What do you want to do? I can expand this, change the description to try explain that it is generating a number between a range/limit, or just close the PR if you think it is an example that it is too broad. No hard feelings :)
I just discovered the
:random.uniform/1function so I tested it against theEnum.random/1that I was using before.I've used the latest Elixir version though as I thought there was no reason to use the older one, I assumed it just hasn't been updated because no one touched the code since the new version got released.
I've followed the "CONTRIBUTING" guideline but let me know if you want me to change anything :)
