Sure - you tell to show 2 decimal places an that happens and you get
111.00 - This is just another representation of the number
111 (content does not change). The same happens with
1 - you get
1.00 and the content doesn’t change.
My default assumption on this English Ask page is (unless the question tells anything else):
decimal separator is:
. (dot) - especially if questioners uses that separator.
Regarding the question: Your question seems to be inspired by accounting machines/calculators, which had a functionality to perform currency calculations without the need to enter decimal separators. I can’t imagine that your desired result could be achieved - even not visually - by doing any formatting, since this would requires “changing content by formatting”.
