Berechnet den Quotienten (das Ergebnis der Expression x/y), Rest (das Ergebnis der Expression x%y) gleichzeitig. (seit C++11)

Original:

Computes the quotient (the result of the expression x/y) and remainder (the result of the expression x%y) simultaneously. (seit C++11)

Berechnet Quotienten und den Rest gleichzeitig. Der Quotient ist die algebraische Quotienten mit einem Bruchteil verworfen (abgeschnitten gegen Null). Der Rest ist derart, dass quot * y + rem == x. (bis C + +11)

Original:

Computes quotient and remainder simultaneously. The quotient is the algebraic quotient with any fractional part discarded (truncated towards zero). The remainder is such that quot * y + rem == x. (bis C + +11)

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.
