Description
Orderings
Documentation
class Eq a => Ord a where Source #
The Ord
class is used for totally ordered datatypes.
Instances of Ord
can be derived for any user-defined datatype whose
constituent types are in Ord
. The declared order of the constructors in
the data declaration determines the ordering in derived Ord
instances. The
Ordering
datatype allows a single comparison to determine the precise
ordering of two objects.
Ord
, as defined by the Haskell report, implements a total order and has the
following properties:
- Comparability
x <= y || y <= x
=True
- Transitivity
- if
x <= y && y <= z
=True
, thenx <= z
=True
- Reflexivity
x <= x
=True
- Antisymmetry
- if
x <= y && y <= x
=True
, thenx == y
=True
The following operator interactions are expected to hold:
x >= y
=y <= x
x < y
=x <= y && x /= y
x > y
=y < x
x < y
=compare x y == LT
x > y
=compare x y == GT
x == y
=compare x y == EQ
min x y == if x <= y then x else y
=True
max x y == if x >= y then x else y
=True
Note that (7.) and (8.) do not require min
and max
to return either of
their arguments. The result is merely required to equal one of the
arguments in terms of (==)
.
Minimal complete definition: either compare
or <=
.
Using compare
can be more efficient for complex types.

The Down
type allows you to reverse sort order conveniently. A value of type
contains a value of type Down
aa
(represented as
).Down
a
If a
has an
instance associated with it then comparing two
values thus wrapped will give you the opposite of their normal sort order.
This is particularly useful when sorting in generalised list comprehensions,
as in: Ord
then sortWith by
.Down
x
>>>
compare True False
GT
>>>
compare (Down True) (Down False)
LT
If a
has a
instance then the wrapped instance also respects
the reversed ordering by exchanging the values of Bounded
and
minBound
.maxBound
>>>
minBound :: Int
-9223372036854775808
>>>
minBound :: Down Int
Down 9223372036854775807
All other instances of

comparing :: Ord a => (b -> a) -> b -> b -> Ordering Source #
comparing p x y = compare (p x) (p y)
Useful combinator for use in conjunction with the xxxBy
family
of functions from Data.List, for example:
... sortBy (comparing fst) ...
clamp :: Ord a => (a, a) -> a -> a Source #
clamp (low, high) a = min high (max a low)
Function for ensuring the value a
is within the inclusive bounds given by
low
and high
. If it is, a
is returned unchanged. The result
is otherwise low
if a <= low
, or high
if high <= a
.
When clamp is used at Double and Float, it has NaN propagating semantics in
its second argument. That is, clamp (l,h) NaN = NaN
, but clamp (NaN, NaN)
x = x
.
>>>
clamp (0, 10) 2
2
>>>
clamp ('a', 'm') 'x'
'm'
