Calcula el cociente y el resto al mismo tiempo. El cociente es el cociente algebraico con cualquier parte fraccionaria descartado (truncado hacia cero). El resto es tal que quot * y + rem == x. (hasta 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. (hasta C++11)

Notas

Hasta que C + +11, la dirección de redondeo del cociente y el signo del resto en el de los operadores integrados de la división y el resto fue definido por la implantación si alguno de los operandos es negativo, pero estaba bien definido en 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.
