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 c99)
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 c99)

[Bearbeiten] Notes

Bis C99 war die Rundung Richtung des Quotienten und das Vorzeichen der Rest in den eingebauten Division und Rest Betreiber Implementierung definiert, wenn einer der Operanden negativ war, aber es war in div gut definierten und ldiv .
Original:
Until C99, 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 div and ldiv.
