# Complex.Pow Method (Complex, Double)

.NET Framework 4

Returns a specified complex number raised to a power specified by a double-precision floating-point number.

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

## Syntax

```'Declaration
Public Shared Function Pow ( _
value As Complex, _
power As Double _
) As Complex
```

#### Parameters

value
Type: System.Numerics.Complex
A complex number to be raised to a power.
power
Type: System.Double
A double-precision floating-point number that specifies a power.

#### Return Value

Type: System.Numerics.Complex
The complex number value raised to the power power.

## Remarks

If value is Complex.Zero, the method returns Complex.Zero. For other values, if power is 0, the method returns Complex.One, and if power is 1, it returns value.

This method corresponds to the Math.Pow method for primitive numeric types.

## Examples

The following example illustrates exponentiation using a complex number and an exponent whose value ranges from -1 to 10.

```
Imports System.Numerics

Module Example
Public Sub Main()
Dim value As New Complex(12, -6)
For power As Integer = -1 To 10
Console.WriteLine("{0} ^ {1,2} = {2:N2}", value, power,
Complex.Pow(value, power))
Next
End Sub
End Module
' The example displays the following output:
'    (12, -6) ^ -1 = (0.07, 0.03)
'    (12, -6) ^  0 = (1.00, 0.00)
'    (12, -6) ^  1 = (12.00, -6.00)
'    (12, -6) ^  2 = (108.00, -144.00)
'    (12, -6) ^  3 = (432.00, -2,376.00)
'    (12, -6) ^  4 = (-9,072.00, -31,104.00)
'    (12, -6) ^  5 = (-295,488.00, -318,816.00)
'    (12, -6) ^  6 = (-5,458,752.00, -2,052,864.00)
'    (12, -6) ^  7 = (-77,822,208.00, 8,118,144.00)
'    (12, -6) ^  8 = (-885,157,632.00, 564,350,976.00)
'    (12, -6) ^  9 = (-7,235,785,728.00, 12,083,157,504.00)
'    (12, -6) ^ 10 = (-14,330,483,712.00, 188,412,604,416.00)
