商(発現x/yの結果)と剰余(発現x%yの結果)を同時に計算します。 (C++11以上)
Original:
Computes the quotient (the result of the expression x/y) and remainder (the result of the expression x%y) simultaneously. (C++11以上)

同時に、商と剰余を計算します。商が(ゼロに向かって切り捨て)に破棄された小数部を持つ代数的な商です。残りはそのようなことquot * y + rem == xです。 (C++11未満)
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. (C++11未満)

ノート
オペランドの片方が陰性であったが、それはstd::divには明確に定義された場合は、C + +11までは、内蔵の除算と剰余演算子で商と剰余の符号の丸め方向は、実装定義であった.
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.
