In Blender 2.92, the measure tool shows distances to the precision of 6 digits after the decimal point, but only integer angle values. This question suggests that previous versions showed two digits after the decimal point.
The linked question has three answers:
copy and paste that value, but I do not know how it is supposed to work;
use N shortcut then "mesh display", but in my version nothing like that shows;
use an extension;
use a script.
Is there a simple way of increasing the precision to at least one digit after the decimal point?
