通过此加载项，可以轻松设置数据表中显示的数据的可见精度。数据不会以任何方式更改，唯一更改的是可见的精度。例如，如果一列具有精度为9位的数据，则可以使精度为3位，但原始的9位仍然存在。在这种情况下，“精度位数”是指小数点右边的位数。
您实际上不需要外接程序即可执行此操作。可以使用列属性来更改列的格式。使用“标准化属性”可以一次在许多列上完成此操作。该视频显示了如何使用所有三种方法来执行此操作：1）使用加载项，2）设置列属性，和3）使用标准化属性。
考虑到可以使用标准的JMP菜单命令轻松完成此操作，因此关于本帖子的最有用的事情可能是将其视为JMP脚本以及如何编写列对话框（选择特定的列来进行操作）的示例。考虑到这一点，我在本文中包含了JSL代码。
如果要加载外接程序，只需将外接程序文件下载到计算机上，然后使用JMP打开该文件。然后，JMP将询问您是否要安装外接程序。
用户界面如下所示：
这是上述三种方法的简短演示视频：
这是该加载项使用的JSL代码：
