[編集] ノート

すべての基本型Tが整数型であるstd::numeric_limits<T>::is_exact==trueいる間、ライブラリは、例えば、整数ではない正確なタイプを定義するかもしれません分数を表す合理的な算術演算の種類.
Original:
While all fundamental types T for which std::numeric_limits<T>::is_exact==true are integer types, a library may define exact types that aren't integers, e.g. a rational arithmetics type representing fractions.
