# Floating-Point Operators for Float Perform arithmetic and bitwise operations or compare values. ## Topics ### Arithmetic [`static func + (Float, Float) -> Float`](/documentation/Swift/Float/+(_:_:)) Adds two values and produces their sum, rounded to a representable value. [`static func - (Float, Float) -> Float`](/documentation/Swift/Float/-(_:_:)) Subtracts one value from another and produces their difference, rounded to a representable value. [`static func * (Float, Float) -> Float`](/documentation/Swift/Float/*(_:_:)) Multiplies two values and produces their product, rounding to a representable value. [`static func / (Float, Float) -> Float`](/documentation/Swift/Float/_(_:_:)) Returns the quotient of dividing the first value by the second, rounded to a representable value. ### Arithmetic with Assignment [`static func += (inout Float, Float)`](/documentation/Swift/Float/+=(_:_:)) Adds two values and stores the result in the left-hand-side variable, rounded to a representable value. [`static func -= (inout Float, Float)`](/documentation/Swift/Float/-=(_:_:)) Subtracts the second value from the first and stores the difference in the left-hand-side variable, rounding to a representable value. [`static func *= (inout Float, Float)`](/documentation/Swift/Float/*=(_:_:)) Multiplies two values and stores the result in the left-hand-side variable, rounding to a representable value. [`static func /= (inout Float, Float)`](/documentation/Swift/Float/_=(_:_:)) Divides the first value by the second and stores the quotient in the left-hand-side variable, rounding to a representable value. ### Comparison [`static func == (Self, Self) -> Bool`](/documentation/Swift/Float/==(_:_:)-12hdt) Returns a Boolean value indicating whether two values are equal. [`static func != (borrowing Self, borrowing Self) -> Bool`](/documentation/Swift/Float/!=(_:_:)) Returns a Boolean value indicating whether two values are not equal. [`static func < (Self, Self) -> Bool`](/documentation/Swift/Float/_(_:_:)-7lwp7) Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument. [`static func <= (Self, Self) -> Bool`](/documentation/Swift/Float/_=(_:_:)-5yoz5) [`static func > (Self, Self) -> Bool`](/documentation/Swift/Float/_(_:_:)-552jr) [`static func >= (Self, Self) -> Bool`](/documentation/Swift/Float/_=(_:_:)-9o6ha) ### Negation [`static func - (Float) -> Float`](/documentation/Swift/Float/-(_:)) Calculates the additive inverse of a value. [`static func + (Self) -> Self`](/documentation/Swift/Float/+(_:)) Returns the given number unchanged. ### Range Expressions [`static func ..< (Self) -> PartialRangeUpTo`](/documentation/Swift/Float/.._(_:)) Returns a partial range up to, but not including, its upper bound. [`static func ... (Self) -> PartialRangeThrough`](/documentation/Swift/Float/...(_:)-4mm65) Returns a partial range up to, and including, its upper bound. [`static func ... (Self) -> PartialRangeFrom`](/documentation/Swift/Float/...(_:)-6ct5t) Returns a partial range extending upward from a lower bound. --- Copyright © 2026 Apple Inc.
