Curried Functions

• In haskell, every function officially takes only one parameter. The way we get to give several parametes to function is by having curried function

> max 4 5
> (max 4) 5

max :: (Ord a) => a-> a -> a
max :: (Ord a) => a-> (a -> a)

• The space in between is funciton application
• You can write partially applied functions. By doing so, we are creating functions on the fly.

multiThree :: (Num a) => a-> a-> a
multiThree x y z = x * y * z

> let multiTwoWithNine = multiThree 9
> multiTwoWithNine 2 3
> 54
