Re: [Haskell-beginners] Repeat function application x times?

Christopher Howard wrote:

Is there a convenient stock function in prelude/base that applies a function to a single value x number of times and returns the result? (I.e., does not return a list, but the final value.) Something like

applyN :: Integral b => (a -> a) -> b -> a -> a

Honestly I looked through the base hierarchy and at hoogle but I am missing it.

No, but it's easy to define: applyN :: Int -> (a -> a) -> a -> a applyN n = foldl (.) id . replicate n Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/
