Hi,
i've one fuction receiving an int . The objective is return the respective binary code of that int.
For example, if i receive 28 the fuction will return 011100.
In GHCi, Prelude> Numeric.showIntAtBase 2 (head . show) 28 $ "" "11100"
My question is that there is any fuction in libraries that do this? If not, anyone has any suggestion?
Other alternatives include, import Data.Bits import Data.List toBinary 0 = "0" toBinary i = reverse (unfoldr nextDigit i) where nextDigit 0 = Nothing nextDigit i = Just (head (show (i .&. 1)), shiftR i 1) or maybe, as you seem to want a certain number of digits, toBinary d i = concatMap show [ fromEnum (testBit i n) | n <- reverse [0..d-1] ] or likewise will work. It's probably best to just use showIntAtBase and pad it with however many 0's you want, though. -- Mark
