Calcola il quoziente (il risultato del x/y espressione) e restante (il risultato del x%y espressione) simultaneamente. (dal C99)

Original:

Computes the quotient (the result of the expression x/y) and remainder (the result of the expression x%y) simultaneously. (dal C99)

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)

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.
