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.
fromEnum :: Enum a => a -> Int
ghc GHC.Prelude.Basic
fromEnum :: EnumSymbolic a => SBV a -> SInteger
sbv Data.SBV Data.SBV.List
fromEnum, same as in the Enum class, except it returns an SInteger
fromEnum :: (Enum a, Bits w) => a -> T w a
enumset Data.EnumBitSet
fromEnum :: (Enum a, Bits w) => a -> MaskedValue w a
enumset Data.FlagSet
fromEnum should return an integer that represents the position of the a value in the list of all enumeration items. In contrast to that, fromEnum must return the according bit pattern.
