  5. class Enum a

    verset Verset

    Class Enum defines operations on sequentially ordered types. The enumFrom... methods are used in Haskell's translation of arithmetic sequences. Instances of Enum may be derived for any enumeration type (types whose constructors have no fields). The nullary constructors are assumed to be numbered left-to-right by fromEnum from 0 through n-1. See Chapter 10 of the Haskell Report for more details. For any type that is an instance of class Bounded as well as Enum, the following should hold:

    enumFrom     x   = enumFromTo     x maxBound
    enumFromThen x y = enumFromThenTo x y bound
    where
    bound | fromEnum y >= fromEnum x = maxBound
    | otherwise                = minBound
    

  6. enumFrom :: Enum a => a -> [a]

    verset Verset

    Used in Haskell's translation of [n..] with [n..] = enumFrom n, a possible implementation being enumFrom n = n : enumFrom (succ n).

    Examples

    • enumFrom 4 :: [Integer] = [4,5,6,7,...]
    • enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound ::
      Int]

  7. enumFromThen :: Enum a => a -> a -> [a]

    verset Verset

    Used in Haskell's translation of [n,n'..] with [n,n'..] = enumFromThen n n', a possible implementation being enumFromThen n n' = n : n' : worker (f x) (f x n'), worker s v = v : worker s (s v), x = fromEnum n' - fromEnum n and

    f n y
    | n > 0 = f (n - 1) (succ y)
    | n < 0 = f (n + 1) (pred y)
    | otherwise = y
    
    

    Examples

    • enumFromThen 4 6 :: [Integer] = [4,6,8,10...]
    • enumFromThen 6 2 :: [Int] = [6,2,-2,-6,...,minBound ::
      Int]

  8. enumFromThenTo :: Enum a => a -> a -> a -> [a]

    verset Verset

    Used in Haskell's translation of [n,n'..m] with [n,n'..m] = enumFromThenTo n n' m, a possible implementation being enumFromThenTo n n' m = worker (f x) (c x) n m, x = fromEnum n' - fromEnum n, c x = bool (>=) ((x 0)

    f n y
    | n > 0 = f (n - 1) (succ y)
    | n < 0 = f (n + 1) (pred y)
    | otherwise = y
    
    
    and
    worker s c v m
    | c v m = v : worker s c (s v) m
    | otherwise = []
    
    

    Examples

    • enumFromThenTo 4 2 -6 :: [Integer] =
      [4,2,0,-2,-4,-6]
    • enumFromThenTo 6 8 2 :: [Int] = []

  9. enumFromTo :: Enum a => a -> a -> [a]

    verset Verset

    Used in Haskell's translation of [n..m] with [n..m] = enumFromTo n m, a possible implementation being

    enumFromTo n m
    | n <= m = n : enumFromTo (succ n) m
    | otherwise = []
    
    

    Examples

    • enumFromTo 6 10 :: [Int] = [6,7,8,9,10]
    • enumFromTo 42 1 :: [Integer] = []

  10. fromEnum :: Enum a => a -> Int

    verset Verset

    Convert to an Int. It is implementation-dependent what fromEnum returns when applied to a value that is too large to fit in an Int.
