Re: [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 ?

'fromIntegral' do 'toFloat' and others convertions. But in your case, using (^) instead of (**) would probably be the good choice. -- Jedaï
