ap -package

ap :: Monad m => m (a -> b) -> m a -> m b
base Control.Monad
In many situations, the liftM operations can be replaced by uses of ap, which promotes function application. > return f `ap` x1 `ap` ... `ap` xn is equivalent to > liftMn f x1 x2 ... xn
ap :: Graph gr => gr a b -> [Node]
fgl Data.Graph.Inductive.Query.ArtPoint
Finds the articulation points for a connected undirected graph, by using the low numbers criteria: a) The root node is an articulation point iff it has two or more children. b) An non-root node v is an articulation point iff there exists at least one child w of v such that lowNumber(w) >= dfsNumber(v).
appendFile :: FilePath -> String -> IO ()
base Prelude, base System.IO
The computation appendFile file str function appends the string str, to the file file. Note that writeFile and appendFile write a literal string to a file. To write a value of any printable type, as with print, use the show function to convert the value to a string first. > main = appendFile "squares" (show [(x,x*x) | x <- [0,0.1..2]])
app :: ArrowApply a => a (a b c, b) c
base Control.Arrow
appEndo :: Endo a -> a -> a
base Data.Monoid
approxRational :: RealFrac a => a -> a -> Rational
base Data.Ratio
approxRational, applied to two real fractional numbers x and epsilon, returns the simplest rational number within epsilon of x. A rational number y is said to be simpler than another y' if * abs (numerator y) <= abs (numerator y'), and * denominator y <= denominator y'. Any real interval contains a unique simplest rational; in particular, note that 0/1 is the simplest rational of all.
