注釈

Addition 演算子を使用すると、複素数を含む加算演算を実行できます。 これにより、次のようなコードが有効になります。

Complex c1 = new Complex(1.2, 2.3);
Complex c2 = new Complex(2.1, 3.2);
Complex c3 = c1 + c2;

let c1 = Complex(1.2, 2.3)
let c2 = Complex(2.1, 3.2)
let c3 = c1 + c2

Dim c1 As New Complex(1.2, 2.3)
Dim c2 As New Complex(2.1, 3.2)
Dim c3 As Complex = c1 + c2

加算によって実数成分または虚数成分のいずれかがオーバーフローする場合、その成分の値は Double.PositiveInfinity または Double.NegativeInfinityのいずれかになります。

カスタム演算子をサポートしていない言語では、代わりに、Add 同等のメソッド グループを呼び出すことができます。

1 つの double を受け取る Addition 演算子は、2 つの複素数を受け取る演算子よりも効率的です。
