Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

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 static void Main()

      Complex complex1 = new Complex(17.34, 12.87);
      Complex complex2 = new Complex(8.76, 5.19);

Remarks

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