From https://www.wikidata.org/wiki/Property_talk:P625#Why_is_60_seconds_possible.3F: "[…] i found another diplay problem (do not know if it is connected). In this item [Q4118348](https://www.wikidata.org/wiki/Q4118348) the second `P625` is displayed to be `36°N, 36°E` but when clicking on it, it links to `36.5867, 37.0458`. This does not seem to be correct."
* Live test: https://www.wikidata.org/w/api.php?action=wbformatvalue&datavalue={"value":{"latitude":36.5867,"longitude":37.0458,"precision":1.1187604885913},"type":"globecoordinate"}
* Cause: bad rounding algorithm in GeoCoordinateFormatter.php
* Expected behavior: 36.5867 and 37.0458 should both be rounded up, display should be `37°N, 37°E`
#patch-for-review:
* [x] https://github.com/DataValues/Geo/pull/95
* [ ] https://github.com/DataValues/Geo/pull/97 updates version number and release notes.
* [ ] I would //love// to see https://github.com/DataValues/Geo/pull/93 in the same release, because it touches the same code, and fixes very closely related rounding issues. But we do not need to block the release because of this. Can also be in a 1.2.3.
* [ ] Tag #datavalues Geo 1.2.2.
* [x] Make sure Wikibase uses it.
* [ ] Possibly update composer.json to require `^1.2.2`.
