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. 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.
There is a function called ROUND which you can use to round to zero decimal places. If your number was in cell A2, the formula would be:
=ROUND(A2,0)
10 to the third power to the tenth power equals ten to the thirtieth power equals one nonillion.
The answer depends on the degree to which the number needs to be rounded.
Since 2735 is an integer, it is already rounded to the nearest fractional part. Rounding the number to the nearest 10 would give 2740.
The answer depends on the units used for 8.275. It should be blindingly obvious to anybody that the answer for 8.275 grams and 8.275 tons, for example, will be very different.
