Complex(Double, Double) Constructor

Definition

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)

Parameters

real
Double

The real part of the complex number.

imaginary
Double

The imaginary part of the complex number.

Examples

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)

Remarks

The real or imaginary arguments may lose precision if they are data types that require an explicit cast to Double.
