operator!= (<complex>)

Tests für Ungleichheit zwischen zwei komplexen Zahlen, eine oder, das möglicherweise gehört der Teilmenge des Typs für das tatsächliche und die imaginären Teile.

template<class Type>
   bool operator!=(
      const complex<Type>& _Left,
      const complex<Type>& _Right
   );
template<class Type>
   bool operator!=(
      const complex<Type>& _Left,
      const Type& _Right
   );
template<class Type>
   bool operator!=(
      const Type& _Left,
      const complex<Type>& _Right
   );

Parameter

  • _Left
    Eine komplexe Zahl oder ein Objekt des für Ungleichheit getestet werden, Parametertyps.

  • _Right
    Eine komplexe Zahl oder ein Objekt des für Ungleichheit getestet werden, Parametertyps.

Rückgabewert

true, wenn die Zahlen nicht gleich sind; false, wenn Zahlen gleich sind.

Hinweise

Zwei komplexe Zahlen sind und wenn gleich nur wenn ihre realen Teil gleich sind, und ihre imaginären Teile sind gleich.Andernfalls sind sie ungleich.

Der Vorgang wird überladen, sodass Vergleichstests ohne die Konvertierung von Daten zu einem bestimmten Format ausgeführt werden können.
