Re: [Haskell-beginners] is there a better way to ask for a hex formatted number?

I am using this currently:

makeHex n = "0x" ++ map toUpper (showHex n "") -- gives me 0xFF for example

I know i can use printf but I am not sending this to output when I am doing the formatting.

printf can also produce Strings: Prelude Text.Printf> printf "0x%x" 239 :: String "0xef" Prelude Text.Printf> printf "0x%X" 239 :: String "0xEF"
