同时计算商和余数。商是代数商的任何小数部分被丢弃（接近零截断）。其余的是这样的，quot * y + rem == x。 （至 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. （至 C++11）

[编辑] 注释
直到商和舍入方向的标志，其余在C + +11，内置的部门和其余运营商实现定义的，如果任一操作数是负的，但它是定义在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.
