1. newtype BinEnum a

   histogram-fill	Data.Histogram.Bin.BinEnum

   Bin for types which are instnaces of Enum type class. Value are converted to Int using fromEnum first and then binned.

2. BinEnum :: BinI -> BinEnum a

   histogram-fill	Data.Histogram.Bin.BinEnum

   No documentation available.

3. binEnum :: Enum a => a -> a -> BinEnum a

   histogram-fill	Data.Histogram.Bin.BinEnum

   Create enum based bin

4. binEnumFull :: (Enum a, Bounded a) => BinEnum a

   histogram-fill	Data.Histogram.Bin.BinEnum

   Use full range of data

5. data BinEnum2D i

   histogram-fill	Data.Histogram.Bin.Extra

   Binning for 2D enumerations

6. class Enum2D a

   histogram-fill	Data.Histogram.Bin.Extra

   Type class very similar to Enum but elements of type are enumerated on 2-dimensional grid

7. binEnum2D :: Enum2D i => i -> i -> BinEnum2D i

   histogram-fill	Data.Histogram.Bin.Extra

   Construct indexed bin

8. fromEnum2D :: Enum2D a => a -> (Int, Int)

   histogram-fill	Data.Histogram.Bin.Extra

   Convert value to index

9. toEnum2D :: Enum2D a => (Int, Int) -> a

   histogram-fill	Data.Histogram.Bin.Extra

   Convert index to value

10. class Enum a

    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:

    • The calls succ maxBound and pred minBound should result in a runtime error.
    • fromEnum and toEnum should give a runtime error if the result value is not representable in the result type. For example, toEnum 7 :: Bool is an error.
    • enumFrom and enumFromThen should be defined with an implicit bound, thus:

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