The fourth decimal place would be the Thousanths place, so rounded it would look like 2,710.00
Hope this helps ;P
This is a whole number there is no indication of a decimal but if you want to round by 1000 then it will be the original number because 1 is not greater than 5.
This is an integer so it cannot be rounded.
Perhaps you want 0.27104?
Then it would be 0.2710 or just 0.271.
You are very welcome!
