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 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. (fino al C99)

[modifica] Note
Fino al C99, la direzione arrotondamento del quoziente e il segno del resto nelle built-in operatori di divisione e il resto è stato definito dall'implementazione se uno degli operandi è stato negativo, ma è stato ben definito in div e 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.
