Hello,

I'm new to haskell, I'm wondering how can you write a function that will do the following:

fromIntToString :: Int -> String

this is a cast function to cast an Int to a String. I know such function exist, however let's assume it didn't exist. How would I write such function?

I have no Idea, but this one works:

intOfChar c | c >= '0' && c <= '9' = fromEnum c - fromEnum '0' intOfChar _ = undefined

this is 'digitToInt' from Char module
