翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク not-a-number ： FOLDOC Not-a-Number (NaN) An {IEEE floating point} representation for the result of a numerical operation which cannot return a valid number value. A NaN can result from multiplying an infinity by a zero, or from subtracting one infinity from another [what else?]. NaN is encoded as a special bit pattern [what pattern?] which would otherwise represent a floating-point number. It is used to signal error returns where other mechanisms are not convenient, e.g. a hardware floating-point unit and to allow errors to propagate through a calculation. Similar bit patterns represent positive and negative overflow and underflow and the positive and negative infinities resulting from {division by zero}. {Bit patterns (http://psc.edu/general/software/packages/ieee/ieee.html)}.
