Haskell: Built in type classes

Following are the important built in type classes.

Type class	Description
Show	Defines the function show, which converts a value into a string, and other related functions.
Read	Defines the function read, which parses a string into a value of the type, and other related functions.
Eq	Equality operators == and /=
Ord	Comparison operators < <= > >=; min, max, and compare.
Enum	For enumerations only. Allows the use of list syntax such as [Blue .. Green].
Bounded	Also for enumerations, but can also be used on types that have only one constructor. Provides minBound and maxBound as the lowest and highest values that the type can take.
