You are interested in the 3rd digit from the right, namely the 1 of 342<b>1</b>12
now look at the digit immediately to the right of that position.
If that digit is < 5, our digit of interest stays the same, all other digits to the
right of our digit of interest become 0
If that digit ≥ 5 we increase our digit of interest by 1, the digits to the right
of it become 0
so you get 342100
(I would have looked at the 112, the hundred value,
since it is < 500, it would simply become 100)
