Add coordinates using QuickStatements, can't figure out the format to use for a SNAK

[Jo]

I try to add the following using QuickStatements:

Q21994182 P625 '0.18852687616471006 31.89817251405117' S854 "http://www.openstreetmap.org"

I tried this too: Q21994182 P625 '0.18852687616471006,31.89817251405117' S854 "http://www.openstreetmap.org"

And this Q21994182 P625 "0.18852687616471006, 31.89817251405117" S854 "http://www.openstreetmap.org"

But then it's not happy about SNAK stuff

According to https://www.wikidata.org/wiki/Topic:Sx36pmqpgnyc3o5o , the syntax is "P625 @3.0941955858894/31.243330502604"
