Int is the type of machine integers, with guaranteed range at least -2^29 to 2^29 - 1, while Integer is arbitrary precision integers, with range as large as you have memory for.
Alright, that was my guess (though I had no idea which was which).
I expect you'll replace ints with a more interesting list, as ints !! i is currently equal to i.
Yeah. I'm actually writing the PRNG component of RC4. I figured that would be a simple yet interesting problem to get started with Haskell. But I wanted to show the most minimal function I could that still illustrates the problem I have.
If you need to coerce something of integral (Int, Integer) type to any numeric type, use fromIntegral.
Okay, I just guessed that I should use it like this:
j = ints !! fromIntegral( i )
That seems to work, so I'll go with it.
Thanks!
