Description

Equality

Synopsis

Documentation

class Eq a where Source #

The Eq class defines equality (== ) and inequality (/= ). All the basic datatypes exported by the Prelude are instances of Eq , and Eq may be derived for any datatype whose constituents are also instances of Eq .

The Haskell Report defines no laws for Eq . However, instances are encouraged to follow these properties:

Reflexivity
x == x = True
Symmetry
x == y = y == x
Transitivity
if x == y && y == z = True , then x == z = True
Extensionality
if x == y = True and f is a function whose return type is an instance of Eq , then f x == f y = True
Negation
x /= y = not (x == y)
