INT関数

本ページには広告が含まれています。

小数点以下を切り落とした数値を返します。

構文

Double = INT( 数値 )

引数

数値（Integer）必須: 数値

戻り値: 小数点以下を切り落とした値を返す

丸める位置

正の数は切り捨てられ、負の数は切り上げられます。

使い方

小数点以下を切り捨てた値を返します。

結果

負の値の場合、正の値のようにより小さい値にではなく0に近い側に切り捨てされます。

言語によっては「-13」と返すものもあるので注意が必要です。

結果

プログラム実行例

Windowsの稼働時間を取得

Windowsシステムの起動時間から稼働時間を求めます。

結果はd:hh:nn:ssの形式で出力されます。
