Complex Constructor

Initializes a new instance of the Complex structure using the specified real and imaginary values.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public Complex(
	double real,
	double imaginary
)

Parameters

real
Type: System.Double

The real part of the complex number.

imaginary
Type: System.Double

The imaginary part of the complex number.

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

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)
