operator+ (<complex>)

Addiert zwei komplexe Zahlen, eine hinzu, oder das möglicherweise der Teilmenge des Typs für das tatsächliche und die Teile imaginären gehört.

      const complex<Type>& _Left, 
      const complex<Type>& _Right

   ); 
template<class Type> 
   complex<Type> operator+( 
      const complex<Type>& _Left 
   );

Parameter

• _Left
  Das erste von zwei Zahlen oder komplexen Zahl aus, die im Parametertyp für eine komplexe Zahl ist, die von hinzugefügt werden soll + Vorgang.

• _Right
  Das zweite von zwei Zahlen oder komplexen Zahl aus, die im Parametertyp für eine komplexe Zahl ist, die von hinzugefügt werden soll + Vorgang.

Rückgabewert

Die komplexe Zahl, die aus der Einführung der beiden Zahlen entsteht, deren Wert und Typ durch den Parameter angegeben werden, gibt ein.

Hinweise

Der Vorgang ist überladen, das einfache mathematische Operationen ohne die die Konvertierung der Daten einem bestimmten Format ausgeführt werden können. Der unäre Operator gibt _Left. zurück

// compile with: /EHsc
#include <complex>
#include <iostream>

   // type complex<double> plus type complex<double>

   cout << "The right-side complex number is cr4 = " << cr4 << endl;
