User blog:FunAlwaysTheGamer/"," and "." at EMC calculation

So well,im just scrolling around the wiki 2 weeks ago and found out a comment where an EMC calculation on an item is messed up, so i counted it myself and well, the results are correct,but it writes something like xxx.xxx, that makes me confused because i read it as hundred-thousands,not hundred-commas(its supposed to be hundred-commas),so i want to ask here which is correct

8.192 EMC for diamonds OR 8,192 EMC for diamonds?(because im pretty confused with this)

i hoped this post is understandable and someoene answered my question
