此插件可以輕鬆設置數據表中顯示的數據的可見精度。數據沒有以任何方式改變，唯一改變的是可見的精度。例如，如果一列有 9 位精度的數據，您可以使 3 位精度可見，但原來的 9 位仍然存在。在這種情況下，“精度位數”是指小數點右側的位數。
您實際上並不需要加載項來執行此操作。可以使用列屬性更改列的格式。這可以使用“標準化屬性”一次在多列上完成。該視頻展示瞭如何使用所有三種方法執行此操作：1) 使用加載項，2) 設置列屬性，以及 3) 使用標準化屬性。
考慮到這可以使用標準的 JMP 菜單命令輕鬆完成，也許這篇文章最有用的地方是將其視為 JMP 腳本的說明以及如何編寫列對話框腳本（選擇特定的列進行操作）。考慮到這一點，我在這篇文章中包含了 JSL 代碼。
如果要加載插件，只需將插件文件下載到您的計算機並使用 JMP 打開文件即可。然後 JMP 將詢問您是否要安裝插件。
用戶界面如下所示：
這是上述所有三種方法的簡短演示視頻：
