protocol IntegerArithmetic The common requirements for types that support integer arithmetic. Inheritance Comparable, Equatable, _IntegerArithmetic View Protocol Hierarchy → Import import Swift Static Methods static func addWithOverflow(_:_:) Required Adds lhs and rhs, returning the result and a Bool that is true iff the operation caused an arithmetic overflow. Declaration static func addWithOverflow(_ lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) Declared In _IntegerArithmetic static func divideWithOverflow(_:_:) Required Divides lhs and rhs, returning the result and a Bool that is true iff the operation caused an arithmetic overflow. Declaration static func divideWithOverflow(_ lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) Declared In _IntegerArithmetic static func multiplyWithOverflow(_:_:) Required Multiplies lhs and rhs, returning the result and a Bool that is true iff the operation caused an arithmetic overflow. Declaration static func multiplyWithOverflow(_ lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) Declared In _IntegerArithmetic static func remainderWithOverflow(_:_:) Required Divides lhs and rhs, returning the remainder and a Bool that is true iff the operation caused an arithmetic overflow. Declaration static func remainderWithOverflow(_ lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) Declared In _IntegerArithmetic static func subtractWithOverflow(_:_:) Required Subtracts lhs and rhs, returning the result and a Bool that is true iff the operation caused an arithmetic overflow. Declaration static func subtractWithOverflow(_ lhs: Self, _ rhs: Self) -> (Self, overflow: Bool) Declared In _IntegerArithmetic Instance Methods func %(_:rhs:) Required Divides lhs and rhs, returning the remainder and trapping in case of arithmetic overflow (except in -Ounchecked builds). Declaration func %(lhs: Self, rhs: Self) -> Self func *(_:rhs:) Required Multiplies lhs and rhs, returning the result and trapping in case of arithmetic overflow (except in -Ounchecked builds). Declaration func *(lhs: Self, rhs: Self) -> Self func +(_:rhs:) Required Adds lhs and rhs, returning the result and trapping in case of arithmetic overflow (except in -Ounchecked builds). Declaration func +(lhs: Self, rhs: Self) -> Self func /(_:rhs:) Required Divides lhs and rhs, returning the result and trapping in case of arithmetic overflow (except in -Ounchecked builds). Declaration func /(lhs: Self, rhs: Self) -> Self 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. Declaration func >=(lhs: Self, rhs: Self) -> Bool Declared In Comparable func -(_:rhs:) Required Subtracts lhs and rhs, returning the result and trapping in case of arithmetic overflow (except in -Ounchecked builds). Declaration func -(lhs: Self, rhs: Self) -> Self func toIntMax() Required Explicitly convert to IntMax, trapping on overflow (except in -Ounchecked builds). Declaration func toIntMax() -> IntMax
