Not applicable
Not applicableは、2つ以上の物体が組み合わない場合や該当しない場合に使われる。例:スポーツの総当たり戦の対戦表で、同じチーム同士が対戦するセル(升目)に記載される。
Not available
Not availableは、データが存在しないか一時的にデータが無い場合に使われる。例:価格表において、まだ販売価格が設定されていない新発売の商品の値段の欄に記載される。
NA
R言語など一部のプログラミング言語ではnot availableをNAと表し、欠損値と訳される。
IEEE 754で定められた例外値ではないので、細部の挙動は言語仕様によるが、通常、NAを含む演算は全て結果がNAになる。そのため、NAかどうかの判定にはNA判定関数が使われる。
これらはNaNに似ているが、NaN==NaNの結果が偽なのに対し、NA==NAの結果はNAである。

This article is about the abbreviation n/a. For other uses of NA, Na and na, see Na.
n/a, which uses lowercase letters, is a common abbreviation for not applicable[1] or not available [citation needed], used to indicate when information in a certain field on a table is not provided, either because it does not apply to a particular case in question or because it is not available. A slash is used to indicate the abbreviation of lowercase words.[citation needed]
NA is an initialism which carries the same latter meaning. A slash is not used in an initialism or acronym. However, the derivative form N/A is in common use.
N/A may also refer to Neurotics Anonymous, predecessor of Emotions Anonymous, which uses N/A to distinguish itself from Narcotics Anonymous (NA)[2]
