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”.
