Is there anybody that can tell what is the purpose of having a "Precision" parameter on Vector | Research Tools | Select by Location?
Where I can find or read about how this "Precision" parameter works?
I'm using QGIS 2.16.2 running on Ubuntu 16.04.1
Answer
Doesn't seem to be a lot of detail available but from the SelectByLocation.py script, it seems to be used for the snapToPrecision() function (again barely any information on this) which requires the feature geometry and a real number as input.
This is then used to create a buffered bounding box of the features for the intersection part.
