When rounding to a specific place, take a look at the digit immediately to the right of the target. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

When rounding off, the rule is, "If the first figure to be discarded is 5 or more then the previous figure is increased by 1. Following this rule then 650 is the result of rounding off numbers in the range 645 to 654. As 650 itself is not rounded off then there are 9 whole numbers that can be rounded to 650.
The rule that is taught in schools is that rounding is determined by the value of the next digit. If it is 4 or less you would simply remove all the digits after the point of rounding. If the digit is 5 or more, you remove all the digits after the point of rounding but also increase the final digit of the rounded number by 1. Unfortunately, this method is flawed because it introduces a systematic bias in the way 5s are rounded. 0 does not need rounding; 1, 2, 3 and 4 should be rounded down; 6, 7, 8 and 9 should be rounded up. The two main ways of rounding 5 is to ensure that the last "surviving" digit is always odd or always even. The IEEE 754 standard is to round to even.
It depends on what you are rounding by. If you are rounding by ten-thousands=80000 If you are rounding by thousands=85000 If you are rounding by hundreds=84700 If you are rounding by tens=84650
Technically, it's closer to neither, but as a rule of rounding, if it's halfway, you round up, so you would round it to 500.

Finding the nearest decimal
While rounding has a few vacations in the field of Economics, most math requires 5/4 rounding. This means to round 1.454 to 1.45 at the hundredths place, but 1.5 at the tenths.
you round it up

it rounds to that number because the number 4 is lower so they take that number out of the picture.
0 is treated just like any other digit: if you are rounding up then it becomes one more and otherwise it remains as it was. So 10600 -> 11000
