Not really true. As far as I remember, the Haskell Report just says that Int
covers
Thanks for the info, and the link.
I probably should have guessed the Double vs Float one. I did program in
C a while ago...
Cheers,

Int is for bounded values -2**32 to 2**32 (I think... maybe 2**-31 and
2**31 or less if it's boxed?) based on the underlying machine
representation. Integer is unbounded (arbitrary precision, i.e.
7489571948579148758174534 is a valid Integer). Double is for floating
point values corresponding to C

Hello all,
I found a good Haskell tutorial (second link on the Tutorials column)
(now that I know how to run the programs in it). I have a question.
What's the difference between the types Int and Integer? Likewise,
what's the difference between the types Float and Double? Are those just
syno

Alright, that was my guess (though I had no idea which was which).
I expect you'll replace ints with

The code you gave, on its own, is fine. The types inferred by ghci are
ints :: [Int]
and
prng :: [[Int]]
Hugs seems to
Hello,
What's the difference between "Int" and "Integer"?
How can I tell Haskell which one I want? I'm having trouble with a function:
ints = 0 : map (1+) ints
prng = map iter ints
where iter 0 = [0,0]
iter n = [i,j]
where i = mod n 256
j = ints
