Complex.Add Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Adds two complex numbers and returns the result.
Namespace: System.Numerics
Assembly: System.Numerics (in System.Numerics.dll)
Syntax
'Declaration
Public Shared Function Add ( _
left As Complex, _
right As Complex _
) As Complex
public static Complex Add(
Complex left,
Complex right
)
Parameters
- left
Type: System.Numerics.Complex
The first complex number to add.
- right
Type: System.Numerics.Complex
The second complex number to add.
Return Value
Type: System.Numerics.Complex
The sum of left and right.
Remarks
The addition of a complex number, a + bi, and a second complex number, c + di, takes the following form:
(a + c) + (b + d)i.
If the method call results in an overflow in either the real or imaginary component, the value of the component is either Double.PositiveInfinity or Double.NegativeInfinity.
Languages that do not support custom operators can use the Add method to perform addition with complex numbers.
Examples
The following example illustrates addition with complex numbers.
Imports System.Numerics
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim values() As Complex = { New Complex(12.3, -1.4),
New Complex(-6.2, 3.1),
New Complex(8.9, 1.5) }
For Each c1 In values
For Each c2 In values
outputBlock.Text += String.Format("{0} + {1} = {2}", c1, c2,
Complex.Add(c1, c2)) + vbCrLf
Next
Next
End Sub
End Module
' The example displays the following output:
' (12.3, -1.4) + (12.3, -1.4) = (24.6, -2.8)
' (12.3, -1.4) + (-6.2, 3.1) = (6.1, 1.7)
' (12.3, -1.4) + (8.9, 1.5) = (21.2, 0.1)
' (-6.2, 3.1) + (12.3, -1.4) = (6.1, 1.7)
' (-6.2, 3.1) + (-6.2, 3.1) = (-12.4, 6.2)
