Same way you do for a top level binding: dec2bin :: Integer -> [Integer] dec2bin n = dec2bin' n [] where dec2bin' :: Integer -> [Integer] -> [Integer] dec2bin' n acc | n == 0 = acc | otherwise = let r = rem n 2 m = div (n - r) 2 in dec2bin' m (r : acc) -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] [email protected] administrator [openafs,heimdal,too many hats] [email protected] and computer engineering, carnegie mellon university KF8NH
