How to generate a random number in Elixir?

Question

I need to generate a random number. I found the Enum.random/1 function, but it expects an enumerable such as a list or range of numbers.

Is that the only way to get a random number?

Answer 1

You can call Erlang's rand module from Elixir code seamlessly.

random_number = :rand.uniform(n)

Will give a random number from 1 <= x <= n
