Adds two complex numbers and returns the result.

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

## Syntax

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.

using System;
using System.Numerics;

public class Example
{
public static void Main()
{
Complex[] values= { new Complex(12.3, -1.4),
new Complex(-6.2, 3.1),
new Complex(8.9, 1.5) };
foreach (var c1 in values)
foreach (var c2 in values)
Console.WriteLine("{0} + {1} = {2}", c1, c2,
}
}
// 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)
//       (-6.2, 3.1) + (8.9, 1.5) = (2.7, 4.6)
//       (8.9, 1.5) + (12.3, -1.4) = (21.2, 0.1)
//       (8.9, 1.5) + (-6.2, 3.1) = (2.7, 4.6)
//       (8.9, 1.5) + (8.9, 1.5) = (17.8, 3)
