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

Public ReadOnly Property Imaginary As Double

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.

Imports System.Numerics

Module Example
   Public Sub Main()
      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
         Console.WriteLine("{0} + {1}i", value.Real, value.Imaginary)
   End Sub
End Module
' The example displays the following output:
'       12.5 + -6.3i
'       -17.8 + 1.7i
'       14.4 + 8.9i
