What happens.. ? Hmm.. if the Rounding is DURING the problem it makes life easier for you.. if it is at the answer, you are either making the no. significantly correct or reducing accuracy.
THere is a SMALL rule... for rounding off that is...
5 and above - Add one to the next place [ 707 ~ 710 ]
Below 5 - Leave the concerned place with a zero.[ 701 ~ 700 ]
But when you are rounding decimals,
Example -
10222.0045
In this case, the no. next to five is an even no., so you DONT add one to it and you replace the 5 with a zero.
10222.0035
In THIS case, the no. next to five is odd so you add one to the 3 next to the 5 and the five is coverted to 0.
Laterz...

You lose some exactness in your answer.
