Operator

+(_:_:)

Adds two values and produces their sum, rounded to a representable value.

Declaration

static func + (lhs: Float, rhs: Float) -> Float

Parameters

lhs

The first value to add.

rhs

The second value to add.

Discussion

The addition operator (+) calculates the sum of its two arguments. For example:

let x = 1.5
let y = x + 2.25
// y == 3.75

The + operator implements the addition operation defined by the IEEE 754 specification.

Arithmetic

static func - (Float, Float) -> Float

Subtracts one value from another and produces their difference, rounded to a representable value.

static func * (Float, Float) -> Float

Multiplies two values and produces their product, rounding to a representable value.

static func / (Float, Float) -> Float

Returns the quotient of dividing the first value by the second, rounded to a representable value.
