Complex(Double, Double) Complex(Double, Double) Complex(Double, Double) Complex(Double, Double) Constructor

定義

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 Double Double Double

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

imaginary
Double Double Double Double

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

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

またrealimaginaryの引数は、へDouble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ます。The real or imaginary arguments may lose precision if they are data types that require an explicit cast to Double.
