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. (до C++11)

Notes

До C + +11, округление направлении частное и знак остатка в встроенным деление и остаток операторов определяется реализацией, если любой из операндов был отрицательным, но это было хорошо определено в 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.
