protocol BinaryInteger Inheritance Arithmetic, Comparable, CustomStringConvertible, Equatable, ExpressibleByIntegerLiteral View Protocol Hierarchy → Associated Types Magnitude : Equatable, ExpressibleByIntegerLiteral IntegerLiteralType A type that represents an integer literal. The standard library integer and floating-point types are all valid types for IntegerLiteralType. Import import Swift Initializers init<T where T : BinaryInteger>(_: T) Declaration init<T where T : BinaryInteger>(_ source: T) init<T where T : FloatingPoint>(_: T) Declaration init<T where T : FloatingPoint>(_ source: T) init(clamping:) Required Declaration init<T where T : BinaryInteger>(clamping source: T) init(extendingOrTruncating:) Required Declaration init<T where T : BinaryInteger>(extendingOrTruncating source: T) init?(exactly:) Declaration init?<T where T : FloatingPoint>(exactly source: T) init(integerLiteral:) Creates an instance initialized to the specified integer value. Do not call this initializer directly. Instead, initialize a variable or constant using an integer literal. For example: let x = 23 In this example, the assignment to the x constant calls this integer literal initializer behind the scenes. value: The value to create. Declaration init(integerLiteral value: Self.IntegerLiteralType) Declared In ExpressibleByIntegerLiteral Static Variables static var isSigned: Bool Required Declaration static var isSigned: Bool { get } Instance Variables var bitWidth: Int Required Declaration var bitWidth: Int { get } var minimumSignedRepresentationBitWidth: Int Required Declaration var minimumSignedRepresentationBitWidth: Int { get } var magnitude: Self.Magnitude Required Declaration var magnitude: Self.Magnitude { get } Declared In Arithmetic var description: String Required A textual representation of this instance. Instead of accessing this property directly, convert an instance of any type to a string by using the String(describing:) initializer. For example: struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)" The conversion of p to a string in the assignment to s uses the Point type's description property. Declaration var description: String { get } Declared In CustomStringConvertible Instance Methods func <(_:rhs:) Required Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument. This function is the only requirement of the Comparable protocol. The remainder of the relational operator functions are implemented by the standard library for any type that conforms to Comparable. Parameters: lhs: A value to compare. rhs: Another value to compare. Declaration func <(lhs: Self, rhs: Self) -> Bool Declared In Comparable func <=(_:rhs:) Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument. Parameters: lhs: A value to compare. rhs: Another value to compare. Declaration func <=(lhs: Self, rhs: Self) -> Bool Declared In Comparable func ==(_:rhs:) Required Returns a Boolean value indicating whether two values are equal. Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false. Parameters: lhs: A value to compare. rhs: Another value to compare. Declaration func ==(lhs: Self, rhs: Self) -> Bool Declared In Equatable func >(_:rhs:) Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument. Parameters: lhs: A value to compare. rhs: Another value to compare. Declaration func >(lhs: Self, rhs: Self) -> Bool Declared In Comparable func >=(_:rhs:) Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument. Parameters: lhs: A value to compare. rhs: Another value to compare.
