Haskell : Type casting Int to String

Question

I know you can convert a String to an number with read like so:

Prelude> read "3" :: Int

3

Prelude> read "3" :: Double

3.0

But how do you grab the string representation of an Int value?

Answer 1

The opposite of read is show.

Prelude> show 3
"3"

Prelude> read $ show 3 :: Int
3
