As far as I understand the patch https://gerrit.wikimedia.org/r/521984, it truncates all coordinates to at most 4 decimal places, even without looking at the precision of the coordinate value. I'm very much concerned about this, as well as confused why this was done. The frontend offers a few precisions to the user. The smallest is "1/10000 of an arcsecond", or 0.000000278 degrees. This requires at least 7 decimal places, better 8 to be sure. The backend does not limit the precision of a coordinate value to anything. It can be as arbitrary as a user of the API wants. The frontend respects arbitrary precisions, displays them, and makes sure they don't get lost when such a value is edited. @WMDE-leszek, may I ask why the patch was merged? Was this in a sprint or discussed anywhere else within the Wikidata team? Also pinging @Lydia_Pintscher because I believe this is now causing actual data loss (within the query service) since 8 weeks.
