Complex.Imaginary Property

Gets the imaginary component of the current Complex object.

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

public double Imaginary { get; }

Property Value

Type: System.Double
The imaginary component of a complex number.

Given a complex number a + bi, the Imaginary property returns the value of b.

The following example instantiates an array of Complex objects and displays the real and imaginary components of each in the form a + bi.

using System;
using System.Numerics;

public class Example
   public static void Main()
      Complex[] values = { new Complex(12.5, -6.3), 
                           new Complex(-17.8, 1.7), 
                           new Complex(14.4, 8.9) };
      foreach (var value in values)
         Console.WriteLine("{0} + {1}i", value.Real, value.Imaginary);
// The example displays the following output: 
//       12.5 + -6.3i 
//       -17.8 + 1.7i 
//       14.4 + 8.9i
