One way of indicating that some or all the zeros are significant is to write the number in scientific notation form (See Section 6). For example, a number such as 2000 would be written as 2 x 103 if it contains one significant figure, and as 2.0 x 103 if it contains two significant figures. Problems: Significant Figures

Example #2 - Round 3.78721 to three significant figures. Look at the fourth figure. It is 7, a number greater than 5, so you round the original number up to 3.79. Example #3 - Round 726.835 to five significant figures. Look at the sixth figure. It is a 5, so now you must look at the fifth figure also.

is the last significant figure that we report. This first uncertain digit has some value because it is our best estimate, and therefore it is included as a significant figure. However, since we are not 100% sure about this uncertain digit, we can not know (and should not report) any numbers further to the right.
