Exemples

L’exemple suivant soustrait chaque nombre complexe dans un tableau d’un nombre complexe :

using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex c1 = new Complex(4.93, 6.87);
      Complex[] values = { new Complex(12.5, 9.6),

                           new Complex(-5.3, -6.6) };

      foreach (var c2 in values)
         Console.WriteLine("{0} - {1} = {2}", c1, c2,
                           Complex.Subtract(c1, c2));

//       (4.93, 6.87) - (4.3, -8.1) = (0.63, 14.97)
//       (4.93, 6.87) - (-1.9, 7.4) = (6.83, -0.53)
//       (4.93, 6.87) - (-5.3, -6.6) = (10.23, 13.47)

Remarques

La méthode Subtract autorise les opérations de soustraction qui impliquent des nombres complexes.

Si la soustraction entraîne un dépassement de capacité dans le composant réel ou imaginaire, la valeur de ce composant est Double.PositiveInfinity ou Double.NegativeInfinity.

Les langages qui prennent en charge les opérateurs personnalisés peuvent également utiliser le groupe d’opérateurs équivalent Subtraction.

Les méthodes Subtract qui reçoivent un double sont plus efficaces que la méthode qui reçoit deux nombres complexes.
