オーバーロード

例

次の例では、複素数の配列内の各要素によって複素数を倍数化します。

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex number1 = new Complex(8.3, 17.5);
      Complex[] numbers = { new Complex(1.4, 6.3),
                            new Complex(-2.7, 1.8),
                            new Complex(3.1, -2.1) };
      foreach (Complex number2 in numbers)
         Console.WriteLine("{0} x {1} = {2}", number1, number2,
                           Complex.Multiply(number1, number2));
   }
}
// The example displays the following output:
//       (8.3, 17.5) x (1.4, 6.3) = (-98.63, 76.79)
//       (8.3, 17.5) x (-2.7, 1.8) = (-53.91, -32.31)
//       (8.3, 17.5) x (3.1, -2.1) = (62.48, 36.82)

注釈

Multiply メソッドを使用すると、複素数を含む乗算演算を実行できます。

乗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。

Multiply メソッドは、カスタム演算子をサポートしていない言語に対して実装されます。 その動作は、乗算演算子を使用した乗算と同じです。
