Complex.Pow Method (Complex, Double)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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
public static Complex Pow(
Complex value,
double power
)
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 Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim value As New Complex(12, -6)
For power As Integer = -1 To 10
outputBlock.Text += String.Format("{0} ^ {1,2} = {2:N2}", value, power,
Complex.Pow(value, power)) + vbCrLf
Next
End Sub
End Module
