指定した実数値と虚数値を使用して Complex 構造体の新しいインスタンスを初期化します。Initializes a new instance of the Complex structure using the specified real and imaginary values.

public:
 Complex(double real, double imaginary);
public Complex (double real, double imaginary);
new System.Numerics.Complex : double * double -> System.Numerics.Complex
Public Sub New (real As Double, imaginary As Double)

パラメーター

real
Double

複素数の実数部。The real part of the complex number.

imaginary
Double

複素数の虚数部。The imaginary part of the complex number.

例

次の例では、2つの複素数をインスタンス化し、加算、減算、乗算、除算演算で使用します。The following example instantiates two complex numbers, and then uses them in addition, subtraction, multiplication, and division operations.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex complex1 = new Complex(17.34, 12.87);
      Complex complex2 = new Complex(8.76, 5.19);

      Console.WriteLine("{0} + {1} = {2}", complex1, complex2,
                                          complex1 + complex2);
      Console.WriteLine("{0} - {1} = {2}", complex1, complex2,
                                          complex1 - complex2);
      Console.WriteLine("{0} * {1} = {2}", complex1, complex2,
                                          complex1 * complex2);
      Console.WriteLine("{0} / {1} = {2}", complex1, complex2,
                                          complex1 / complex2);
   }
}
// The example displays the following output:
//    (17.34, 12.87) + (8.76, 5.19) = (26.1, 18.06)
//    (17.34, 12.87) - (8.76, 5.19) = (8.58, 7.68)
//    (17.34, 12.87) * (8.76, 5.19) = (85.1031, 202.7358)
//    (17.34, 12.87) / (8.76, 5.19) = (2.10944241403558, 0.219405693054265)

注釈

realまたはの引数は、 imaginary への明示的なキャストを必要とするデータ型である場合、有効桁数が失われる可能性があり Double ます。The real or imaginary arguments may lose precision if they are data types that require an explicit cast to Double.
