[Haskell-cafe] How to convert number types.

Hi MailList Haskell-Cafe: I am a new haskeller. And was farmilar with C. When tring to do some calculate, like this: input = 5 :: Int factor = 1.20 :: Float output = factor ** (toFloat input) I found that I do not know any function could do just what 'toFloat' should do. What should I do then ? Regards -------------- L.Guo 2008-01-01
