easy question: transform Float -> Int how?
If I have a value of type Float, and I want to pass it (approximately rounded) to a function wanting an Int, how do I do that?
Use the round function (or ceiling or floor).

Hi John,
This page http://www.haskell.org/haskellwiki/Converting_numbers should
have you covered. Check section 3 especially.
Thanks,
Arjun

Very nice—thanks for the link. David: I must have overlooked round,truncate,ceiling. I think I didn't realize that they don't return the same type that they take as argument. Anyway, "round" worked. Thanks!
