It’s 3.000 Heres a lil rhyme that helped me with rounding “If it’s 5 or more, up the score. If it’s 4 or less let it rest.” So since 8 is higher than 5, you want to just go to the number after 2.
The thousandth number is the third number in the provided integer, you round down because the ten-thousandth value is 1, and you will only round up if the number is 5 or higher, otherwise, you round down.
