I understand now. The value given is well within the precision, not even very far off. The problem then is that it is misleading. Someone who reads the wikidata page to program a GPS will end up 356 m from that building.

I think the problem is that, in order to find out that there is a non-negligible precision involved, you need to actually try to edit the value; that's something most people will never do. It would be a lot more helpful to display both the central value and the precision, side by side.

Incidentally, the question is who entered four decimals of coordinates and then gave a precision of a hundredth of a degree? Looking at the history, it was a bot importing from the English Wikipedia. Nothing in the article suggests that figure for the precision, so it's probably a bug in the bot, which "invented" a precision for those coordinates.
