Is there a way to change the number of shown decimal places for the coordinates in the Vertex Editor of QGIS 3.x?

enter image description here

So instead of displaying 9.4324, I want to have it to show me 9.4323669648.

    I don't know if this is possible but if 4 decimal may not provide the accuracy you need 10 decimal seem a bit to much and will be harder to read (check this https://gis.stackexchange.com/questions/8650/measuring-accuracy-of-latitude-and-longitude to help you determine how many decimal will be useful for you) – J.R Sep 13 '21 at 15:28

The number of digits shown in Vertex Tool is tied to the value in your project settings:

Menu Project->Properites General tab -> Coordinate and Bearing Display Set Coordinate precision to Manual and input the number of decimal places you would like to be shown:

In this case I set it to 7 digits, and that is what I now see in Vertex Tool:

Note 1: you need to close and reopen Vertex Tool to view the change

Note 2: Not sure about the reasons why you need such an extreme number of decimal places, however consider this XKCD as a serious reference about the reasonable number of decimal places to adopt ;) :

    Thanks, this one solved my problem. FYI the value was just an example. I'm developing an application and wanted a way to identify vertices. However, the decimal places 4 was not enough for me. – kwarr Sep 13 '21 at 16:46

    I guess at least someone here on GIS SE went on a sat imagery of sort to look if at that very precise coordinate there was a treasure trove :D – RafDouglas C. Tommasi Sep 13 '21 at 17:08
  • For some reason, this does not work in QGIS 3.16.14, still displaying 3 decimal places.

    Also, I don't agree on your number of digits and meaning. For example, calculating the line length of 0.0001 degrees E/W yields 7.169 meters (WGS 84, 'LINESTRING (2 50, 2.0001 50)' ). This will of course vary depending on position.

    For that reason we're using 7 decimal places in our case.

    For a projected coordinate system, 3 decimals is more than enough in most cases.
