The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Divides one complex number by another and returns the result.

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

public static Complex Divide(
	Complex dividend,
	Complex divisor


Type: System.Numerics.Complex

The complex number to be divided.

Type: System.Numerics.Complex

The complex number to divide by.

Return Value

Type: System.Numerics.Complex

The quotient of the division.

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.

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

using System;
using System.Numerics;

public class Example
   public static void Main()
      Complex c1 = new Complex(1.2, 2.3);
      Complex[] values = { new Complex(1.2, 2.3), 
                           new Complex(0.5, 0.75), 
                           new Complex(3.0, -5.0) };
      foreach (Complex c2 in values)
         Console.WriteLine("{0} / {1} = {2:N2}", c1, c2, 
                           Complex.Divide(c1, c2));
// 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)
