Operator 演算子

+(_:_:)

Adds two values and produces their sum. ２つの値を加算してそれらの合計を生成します。

Declaration 宣言 

static func + (lhs: AnimatablePair<First, Second>, rhs: AnimatablePair<First, Second>) -> AnimatablePair<First, Second>

Parameters パラメータ

lhs

The first value to add. 加算する第１の値。

rhs

The second value to add. 加算する第２の値。

Discussion 議論

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


1 + 2                   // 3
-10 + 15                // 5
-15 + -5                // -20
21.5 + 3.25             // 24.75

You cannot use + with arguments of different types. To add values of different types, convert one of the values to the other value’s type.


let x: Int8 = 21
let y: Int = 1000000
Int(x) + y              // 1000021

Manipulating Animations

static var zero: AnimatablePair<First, Second>
The zero value. ゼロ値。
static func += (inout AnimatablePair<First, Second>, AnimatablePair<First, Second>)
Adds two values and stores the result in the left-hand-side variable. ２つの値を加算して、結果を左手側の変数に格納します。
static func - (AnimatablePair<First, Second>, AnimatablePair<First, Second>) -> AnimatablePair<First, Second>
Subtracts one value from another and produces their difference.
static func -= (inout AnimatablePair<First, Second>, AnimatablePair<First, Second>)
Subtracts the second value from the first and stores the difference in the left-hand-side variable. ２番目の値を最初のものから減じて、その差を左手側の変数の中に格納します。
var magnitudeSquared: Double
The dot-product of this animated pair with itself.
func scale(by: Double)
Multiplies each component of this value by the given value. この値の各構成要素をこの与えられた値で乗算します。
