Any way to shown full precision when mouse cursor on it, but show rounding

Dear all,

I have such senario need to implement, show full precision when mouse cursor on it, but show rounding result at first shown,
any way to implement this? pls ignore the roudning logic, I have done it. Just want to know if anyway to display like this?

Do you mean that full precision will be shown in a tooltip?
It’s quite easy, set the value (setValue) of the field to the rounded value, and the tooltip (setDescription) to the full value.

If you want to display the full value in the field itself on mouse over, it requires some client-side coding. Not too difficult if you know client-side coding in general.
