Complex Constructor (Double, Double)

 

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)

Public Sub New (
	real As Double,
	imaginary As Double
)

Parameters

real
Type: System.Double

The real part of the complex number.

imaginary
Type: System.Double

The imaginary part of the complex number.

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

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

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim complex1 As New Complex(17.34, 12.87)
      Dim Complex2 As 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)
   End Sub
End Module
' The example displays the following output:

'    (17.34, 12.87) * (8.76, 5.19) = (85.1031, 202.7358)
'    (17.34, 12.87) / (8.76, 5.19) = (2.10944241403558, 0.219405693054265)
