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? Cause I have no idea, because there are infinity possibilities if I do it like:

 

fromIntToString x | x == 1 = "1"

                         | x == 2 = "2"

-- And so on...

 

I've also thinked about defining the defining the data types Int and String (I know you cannot redefine them, at least I think so), however I've no succes.

 

Thank you in advance for answering my question!

 

PS: if possible please do not use any casting functions that are predefined.
