# SignedInteger Implementations ## Topics ### Initializers [`init(T)`](/documentation/Swift/Int128/init(_:)-7lln8) Creates a new instance from the given integer. [`init?(exactly: T)`](/documentation/Swift/Int128/init(exactly:)-7udqs) ### Instance Methods [`func dividingFullWidth((high: Self, low: Self.Magnitude)) -> (quotient: Self, remainder: Self)`](/documentation/Swift/Int128/dividingFullWidth(_:)) ### Type Properties [`static var isSigned: Bool`](/documentation/Swift/Int128/isSigned) A Boolean value indicating whether this type is a signed integer type. [`static var max: Self`](/documentation/Swift/Int128/max-4kic7) The maximum representable integer in this type. [`static var min: Self`](/documentation/Swift/Int128/min-42rpc) The minimum representable integer in this type. --- Copyright © 2026 Apple Inc.
