# Complex.Divide Method

Visual Studio 2010

Divides one complex number by another and returns the result.

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

## Syntax

```'Declaration
Public Shared Function Divide ( _
dividend As Complex, _
divisor As Complex _
) As Complex
```

#### Parameters

dividend
Type: System.Numerics.Complex
The complex number to be divided.
divisor
Type: System.Numerics.Complex
The complex number to divide by.

#### Return Value

Type: System.Numerics.Complex
The quotient of the division.

## Remarks

The division of a complex number, a + bi, by a second complex number, number, c + di, takes the following form:

((ac + bd) / (c2 + d2)) + ((bc - ad) / (c2 + d2)i

If the calculation of the quotient results in an overflow in either the real or imaginary component, the value of that component is either Double.PositiveInfinity or Double.NegativeInfinity.

The Divide method can be used by languages that do not support custom operators. Its behavior is identical to division using the division operator.

## Examples

The following example divides a complex number by each element in an array of complex numbers.

```
Imports System.Numerics

Module Example
Public Sub Main()
Dim c1 As New Complex(1.2, 2.3)
Dim values() As Complex = { New Complex(1.2, 2.3),
New Complex(0.5, 0.75),
New Complex(3.0, -5.0) }
For Each c2 In values
Console.WriteLine("{0} / {1} = {2:N2}", c1, c2,
Complex.Divide(c1, c2))
Next
End Sub
End Module
' The example displays the following output:
'       (1.2, 2.3) / (1.2, 2.3) = (1.00, 0.00)
'       (1.2, 2.3) / (0.5, 0.75) = (2.86, 0.31)
'       (1.2, 2.3) / (3, -5) = (-0.23, 0.38)

```
