Data.Bounded

class (Ord a) <= Bounded a  where

The Bounded type class represents totally ordered types that have an upper and lower boundary.

Instances should satisfy the following law in addition to the Ord laws:

• Bounded: bottom <= a <= top

Members

• top :: a
• bottom :: a

Instances

• Bounded Boolean
• Bounded Int

  The Bounded Int instance has top :: Int equal to 2^31 - 1, and bottom :: Int equal to -2^31, since these are the largest and smallest integers representable by twos-complement 32-bit integers, respectively.

• Bounded Char

  Characters fall within the Unicode range.

• Bounded Ordering
• Bounded Unit
• Bounded Number

data Ordering

The Ordering data type represents the three possible outcomes of comparing two values:

LT - The first value is less than the second. GT - The first value is greater than the second. EQ - The first value is equal to the second.

Constructors

• LT
• GT
• EQ

Instances

• Eq Ordering
• Semigroup Ordering
• Show Ordering

class (Eq a) <= Ord a  where

The Ord type class represents types which support comparisons with a total order.

Ord instances should satisfy the laws of total orderings:

• Reflexivity: a <= a
• Antisymmetry: if a <= b and b <= a then a = b
• Transitivity: if a <= b and b <= c then a <= c

Members

• compare :: a -> a -> Ordering

Instances

• Ord Boolean
• Ord Int
• Ord Number
• Ord String
• Ord Char
• Ord Unit
• Ord Void
• (Ord a) => Ord (Array a)
• Ord Ordering
