Display thousands during data entry

exist any way to show thousand separator during data entry ?
display format only show it after edit and i didn’t find a way with entry filter.
unfortunately we work with big numbers and it’s easy to make a mistake if you don’t see it during data entry .

If the number of digits in the big numbers is always the same, it’s possible with a filter. If it varies, I think you have to use a text input to mimic the format.

some code to start with:

Yes, a can try to manage the problem using a text variable and manually define how is written.
I continue to think that is a non efficient way to do it.
convert variable from and to text means for me to manage a lot of double variable.
however… i have simplified your procedure with this.
