hi, i believe you should use fromIntegral :: (Integral a, Num b) => a -> b
Since Int is in the Integral class, and Float is in the Num class this should do exactly the job you need.
For the other functions that were not working --- they were moved to the Char module, so you need to add "import Char" at the top of your program.

fromInt = fromInteger . toInteger
this does not seem like a good idea, as you start with an Int, then convert it to an Integer, and then you make a Float out of that. seems like a waste.
hope this helps -iavor

fromInteger works, but it converts from Integer to Float. In my script, I need fromInt because it converts from Int to Float.
Example:
average :: Int -> Float average n = fromInt ( sum n ) :: Float / fromInt n :: Float
It works only in Hugs November 2002

I'm too lazy to check the standard, so I'll just assume Hugs was wrong. I think the solution is to use "fromIntegral" instead. GHCi also has "fromInteger", although I'm not quite sure why we need this in addition to "fromIntegral"? (Possibly because it is a member of Num, and it would break too much code to remove it)
