    [Bearbeiten]Notes

    Bis C + 11, die Rundung Richtung des Quotienten und das Vorzeichen der Rest in der integrierten Teilung und Rest Betreibern Implementierung definiert, wenn einer der Operanden negativ war, aber es war in std::div wohldefinierte .
    Original:
    Until C++11, the rounding direction of the quotient and the sign of the remainder in the built-in division and remainder operators was implementation-defined if either of the operands was negative, but it was well-defined in std::div.
