Esempio

L'esempio seguente illustra l'aggiunta con numeri complessi:

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, 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)

Commenti

L'operatore Addition consente di eseguire operazioni di addizione che coinvolgono numeri complessi. Abilita codice come il seguente:

Complex c1 = new Complex(1.2, 2.3);
Complex c2 = new Complex(2.1, 3.2);
Complex c3 = c1 + c2;

let c1 = Complex(1.2, 2.3)
let c2 = Complex(2.1, 3.2)
let c3 = c1 + c2

Dim c1 As New Complex(1.2, 2.3)
Dim c2 As New Complex(2.1, 3.2)
Dim c3 As Complex = c1 + c2

Se l'addizione comporta un overflow nel componente reale o immaginario, il valore di tale componente è Double.PositiveInfinity o Double.NegativeInfinity.

I linguaggi che non supportano operatori personalizzati possono invece chiamare il gruppo di metodi equivalente Add.

Gli operatori Addition che ricevono un doppio sono più efficienti degli operatori che ricevono due numeri complessi.
