Calcola il quoziente (il risultato del x/y espressione) e restante (il risultato del x%y espressione) simultaneamente. (dal C++11)
Original:

Calcola quoziente e resto contemporaneamente. Il quoziente è il quoziente algebrica con qualsiasi parte frazionaria scartata (troncato a zero). Il resto è tale che quot * y + rem == x. (fino al 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. (fino al c++11)

[modifica] Note
Fino al C + +11, la direzione arrotondamento del quoziente e il segno del resto nel built-in operatori di divisione e resto è stato definito dall'implementazione se uno degli operandi è stato negativo, ma è stato ben definito in std::div.
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.
