protocol _SignedNumberType This protocol is an implementation detail of SignedNumberType; do not use it directly. Its requirements are inherited by SignedNumberType and thus must be satisfied by types conforming to that protocol. Inheritance Comparable, Equatable, IntegerLiteralConvertible, _Comparable View Protocol Hierarchy → Associated Types IntegerLiteralType Import import Swift Initializers init(integerLiteral:) Required Create an instance initialized to value. Declaration init(integerLiteral value: IntegerLiteralType) Declared In IntegerLiteralConvertible Instance Methods func <(_:rhs:) Required A strict total order over instances of Self Declaration func <(lhs: Self, rhs: Self) -> Bool Declared In _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 Declared In Equatable func >(_:rhs:) Declaration func >(lhs: Self, rhs: Self) -> Bool Declared In Comparable func >=(_:rhs:) Declaration func >=(lhs: Self, rhs: Self) -> Bool Declared In Comparable func -(_:rhs:) Required Return the difference between lhs and rhs. Declaration func -(lhs: Self, rhs: Self) -> Self
