## AbsoluteValuable

protocol AbsoluteValuable

A type that supports an "absolute value" function.

### Initializers

init(integerLiteral:) Required

Create an instance initialized to value.

#### Declaration

init(integerLiteral value: Self.IntegerLiteralType)

#### Declared In

IntegerLiteralConvertible

### Static Methods

static func abs(_:) Required

Returns the absolute value of x.

#### Declaration

static func abs(x: Self) -> Self

### Instance Methods

func <(_:rhs:) Required

A strict total order over instances of Self.

#### Declaration

func <(lhs: Self, rhs: Self) -> Bool

Comparable
func <=(_:rhs:)

#### Declaration

func <=(lhs: Self, rhs: Self) -> Bool

#### Declared In

Comparable
func ==(_:rhs:) Required

Return true if lhs is equal to rhs.

Equality implies substitutability. When x == y, x and y are interchangeable in any code that only depends on their values.

Class instance identity as distinguished by triple-equals === is notably not part of an instance's value. Exposing other non-value aspects of Equatable types is discouraged, and any that are exposed should be explicitly pointed out in documentation.

Equality is an equivalence relation

• x == x is true
• x == y implies y == x
• x == y and y == z implies x == z

Inequality is the inverse of equality, i.e. !(x == y) iff x != y.

#### Declaration

func ==(lhs: Self, rhs: Self) -> Bool

Equatable
func >(_:rhs:)

#### Declaration

func >(lhs: Self, rhs: Self) -> Bool

Comparable
func >=(_:rhs:)

#### Declaration

func >=(lhs: Self, rhs: Self) -> Bool

#### Declared In

Comparable
prefix func -(_:) Required

Return the result of negating x.

#### Declaration

prefix func -(x: Self) -> Self

#### Declared In

SignedNumberType
func -(_:rhs:) Required

Return the difference between lhs and rhs.

#### Declaration

func -(lhs: Self, rhs: Self) -> Self

SignedNumberType
