Complex Constructor

.NET Framework 4

Other Versions

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)

Syntax

C++

Copy

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.

Remarks

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

Examples

The following example instantiates two complex numbers, and then uses them in addition, subtraction, multiplication, and division operations.

Copy


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)
