# Binary Integer Operators Perform arithmetic and bitwise operations or compare values. ## Topics ### Arithmetic [`static func + (Self, Self) -> Self`](/documentation/Swift/BinaryInteger/+(_:_:)) Adds two values and produces their sum. [`static func - (Self, Self) -> Self`](/documentation/Swift/BinaryInteger/-(_:_:)) Subtracts one value from another and produces their difference. [`static func * (Self, Self) -> Self`](/documentation/Swift/BinaryInteger/*(_:_:)) Multiplies two values and produces their product. [`static func / (Self, Self) -> Self`](/documentation/Swift/BinaryInteger/_(_:_:)-8zc6l) Returns the quotient of dividing the first value by the second. ### Arithmetic with Assignment [`static func += (inout Self, Self)`](/documentation/Swift/BinaryInteger/+=(_:_:)) Adds two values and stores the result in the left-hand-side variable. [`static func -= (inout Self, Self)`](/documentation/Swift/BinaryInteger/-=(_:_:)) Subtracts the second value from the first and stores the difference in the left-hand-side variable. [`static func *= (inout Self, Self)`](/documentation/Swift/BinaryInteger/*=(_:_:)) Multiplies two values and stores the result in the left-hand-side variable. [`static func /= (inout Self, Self)`](/documentation/Swift/BinaryInteger/_=(_:_:)-20xv1) Divides the first value by the second and stores the quotient in the left-hand-side variable. ### Bitwise Operations [`static func & (Self, Self) -> Self`](/documentation/Swift/BinaryInteger/&(_:_:)) Returns the result of performing a bitwise AND operation on the two given values. [`static func &= (inout Self, Self)`](/documentation/Swift/BinaryInteger/&=(_:_:)) Stores the result of performing a bitwise AND operation on the two given values in the left-hand-side variable. [`static func ~ (Self) -> Self`](/documentation/Swift/BinaryInteger/~(_:)) Returns the inverse of the bits set in the argument. ### Bit Shift ### Comparison [`static func != (Self, Other) -> Bool`](/documentation/Swift/BinaryInteger/!=(_:_:)-9ooa7) Returns a Boolean value indicating whether the two given values are not equal. [`static func != (Self, Self) -> Bool`](/documentation/Swift/BinaryInteger/!=(_:_:)-4ljme) Returns a Boolean value indicating whether two values are not equal. --- Copyright © 2026 Apple Inc.
