[編集] ノート

組み込みの引数のいずれかまたは両方がNaNの場合operator<とoperator>浮動小数点数のためのFE_INVALIDを上げるかもしれません。この関数は、式x < y || x > yの "静かな"バージョンです.
Original:
The built-in operator< and operator> for floating-point numbers may raise FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of the expression x < y || x > y.
