Calcula o quociente eo resto simultaneamente. O quociente é o quociente algébrica com qualquer parte fracionária descartado (truncado para zero). O restante é quot * y + rem == x que tais. (até 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. (até C + 11)

[editar] Notas

Até C + 11, a direção do arredondamento do quociente eo sinal do restante no built-in operadores de divisão e resto foi definida pela implementação se um dos operandos foi negativo, mas foi bem definido no 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.
