Hi, I'm CiaPan. You have recently replaced a period with a comma in Stereographic projection (specifically, in this edit). Your change got reverted and then restored, after which the reverting user started a relevant discussion at Talk:Stereographic projection#Punctuation dispute.
I invite you to join the talk. --CiaPan (talk) 17:04, 19 June 2021 (UTC)
