This module is intended to replace the functionality of {{Coord}} and related
templates. It provides several methods, including
{{#Invoke:Coordinates | coord }} : General function formatting and displaying
coordinate values.
{{#Invoke:Coordinates | dec2dms }} : Simple function for converting decimal
degree values to DMS format.
{{#Invoke:Coordinates | dms2dec }} : Simple function for converting DMS format
to decimal degree format.

wd_coord, hämtar geografisk koordinat (property P625) från wikidata för sidan med funktionsanropet och returnerar resultatet av anrop till functionen Coordinates:coord
om funktionen anropas från en sida som saknar geografisk koordinat i wikidata så returneras parametrar motsvarande latitud 0 och longitud 0.
latitud och longitud avrundas i enlighet med värdet på precision (som är en del av P625).
