Gets the real component of the current Complex object.

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

Syntax

'Declaration
Public ReadOnly Property Real As Double

public double Real { get; }

Property Value

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

Remarks

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

Examples

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

Imports System.Numerics

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim values() As Complex = { New Complex(12.5, -6.3), 
                                  New Complex(-17.8, 1.7), 
                                  New Complex(14.4, 8.9) }
      For Each value In values
         outputBlock.Text += String.Format("{0} + {1}i", value.Real, value.Imaginary) & vbCrLf
      Next
   End Sub
End Module
' The example displays the following output:
'       12.5 + -6.3i
'       -17.8 + 1.7i
'       14.4 + 8.9i

using System;
using System.Numerics;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      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)
         outputBlock.Text += String.Format("{0} + {1}i", value.Real, value.Imaginary) + "\n";
   }
}
// The example displays the following output:
//       12.5 + -6.3i
//       -17.8 + 1.7i
//       14.4 + 8.9i
