通過此加載項，可以輕鬆設置數據表中顯示的數據的可見精度。數據不會以任何方式更改，唯一更改的是可見的精度。例如，如果一列具有精度為9位的數據，則可以使精度為3位，但原始的9位仍然存在。在這種情況下，“精度位數”是指小數點右邊的位數。
您實際上不需要外接程序即可執行此操作。可以使用列屬性來更改列的格式。使用“標準化屬性”可以一次在許多列上完成此操作。該視頻顯示瞭如何使用所有三種方法來執行此操作：1）使用加載項，2）設置列屬性，和3）使用標準化屬性。
考慮到可以使用標準的JMP菜單命令輕鬆完成此操作，因此關於本帖子的最有用的事情可能是將其視為JMP腳本以及如何編寫列對話框（選擇特定的列來進行操作）的示例。考慮到這一點，我在本文中包含了JSL代碼。
如果要加載外接程序，只需將外接程序文件下載到計算機上，然後使用JMP打開該文件。然後，JMP將詢問您是否要安裝外接程序。
用戶界面如下所示：
這是上述三種方法的簡短演示視頻：
