# FixedWidthInteger Implementations ## Topics ### Operators [`static func &* (Self, Self) -> Self`](/documentation/Swift/Int32/&*(_:_:)) Returns the product of the two given values, wrapping the result in case of any overflow. [`static func &*= (inout Self, Self)`](/documentation/Swift/Int32/&*=(_:_:)) Multiplies two values and stores the result in the left-hand-side variable, wrapping any overflow. [`static func &+ (Self, Self) -> Self`](/documentation/Swift/Int32/&+(_:_:)) Returns the sum of the two given values, wrapping the result in case of any overflow. [`static func &+= (inout Self, Self)`](/documentation/Swift/Int32/&+=(_:_:)) Adds two values and stores the result in the left-hand-side variable, wrapping any overflow. [`static func &- (Self, Self) -> Self`](/documentation/Swift/Int32/&-(_:_:)) Returns the difference of the two given values, wrapping the result in case of any overflow. [`static func &-= (inout Self, Self)`](/documentation/Swift/Int32/&-=(_:_:)) Subtracts the second value from the first and stores the difference in the left-hand-side variable, wrapping any overflow. [`static func &<< (Self, Other) -> Self`](/documentation/Swift/Int32/&__(_:_:)-1djlp) Returns the result of shifting a value’s binary representation the specified number of digits to the left, masking the shift amount to the type’s bit width. [`static func &>> (Self, Other) -> Self`](/documentation/Swift/Int32/&__(_:_:)-2odv2) Returns the result of shifting a value’s binary representation the specified number of digits to the right, masking the shift amount to the type’s bit width. [`static func &>> (Self, Self) -> Self`](/documentation/Swift/Int32/&__(_:_:)-5dixx) Returns the result of shifting a value’s binary representation the specified number of digits to the right, masking the shift amount to the type’s bit width. [`static func &<< (Self, Self) -> Self`](/documentation/Swift/Int32/&__(_:_:)-6cb7m) Returns the result of shifting a value’s binary representation the specified number of digits to the left, masking the shift amount to the type’s bit width. [`static func &>> (Int32, Int32) -> Int32`](/documentation/Swift/Int32/&__(_:_:)-7sh72) Returns the result of shifting a value’s binary representation the specified number of digits to the right, masking the shift amount to the type’s bit width. [`static func &<< (Int32, Int32) -> Int32`](/documentation/Swift/Int32/&__(_:_:)-98mep) Returns the result of shifting a value’s binary representation the specified number of digits to the left, masking the shift amount to the type’s bit width. [`static func &<<= (inout Self, Other)`](/documentation/Swift/Int32/&__=(_:_:)-1642g) Returns the result of shifting a value’s binary representation the specified number of digits to the left, masking the shift amount to the type’s bit width, and stores the result in the left-hand-side variable. [`static func &>>= (inout Self, Other)`](/documentation/Swift/Int32/&__=(_:_:)-7weao) Calculates the result of shifting a value’s binary representation the specified number of digits to the right, masking the shift amount to the type’s bit width, and stores the result in the left-hand-side variable. ### Initializers [`init?(String)`](/documentation/Swift/Int32/init(_:)-6wz3b) Creates a new integer value from the given string. [`init(T)`](/documentation/Swift/Int32/init(_:)-97yta) [`init?(S, radix: Int)`](/documentation/Swift/Int32/init(_:radix:)) Creates a new integer value from the given string and radix. [`init(bigEndian: Self)`](/documentation/Swift/Int32/init(bigEndian:)) Creates an integer from its big-endian representation, changing the byte order if necessary. [`init?(exactly: T)`](/documentation/Swift/Int32/init(exactly:)-77qpt) [`init(littleEndian: Self)`](/documentation/Swift/Int32/init(littleEndian:)) Creates an integer from its little-endian representation, changing the byte order if necessary. ### Instance Properties [`var bigEndian: Self`](/documentation/Swift/Int32/bigEndian) The big-endian representation of this integer. [`var littleEndian: Self`](/documentation/Swift/Int32/littleEndian) The little-endian representation of this integer. ### Type Methods [`static func random(in: Range) -> Self`](/documentation/Swift/Int32/random(in:)-47fh7) Returns a random value within the specified range. [`static func random(in: ClosedRange) -> Self`](/documentation/Swift/Int32/random(in:)-4xbuz) Returns a random value within the specified range. [`static func random(in: Range, using: inout T) -> Self`](/documentation/Swift/Int32/random(in:using:)-2c18d) Returns a random value within the specified range, using the given generator as a source for randomness. [`static func random(in: ClosedRange, using: inout T) -> Self`](/documentation/Swift/Int32/random(in:using:)-thxt) Returns a random value within the specified range, using the given generator as a source for randomness. --- Copyright © 2026 Apple Inc.
