A number that is closer to zero than it is to 100,000 will round to zero. This will generally be all numbers equal to 49,999 or less.
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the second greatest place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
Zero.
The answer is 0.
It will round to zero.
Whatever the greatest place is, look at the number immediately to the right of it. If that number is 4 or lower, zero it and everything to the right of it out. If that number is 5 or higher, increase the greatest place by one and zero everything to the right of it out.

It is 0.5
The greatest nonzero place is the number closest to the left (or the greatest number) that is not zero. So in this example, that would be the 8. So you would round the 8 up to a 9 (since 6 is greater than 4). So your answer would be 0.9
