Editing Significant figures (section)

=== Round only on the final calculation result ===
When performing multiple stage calculations, do not round intermediate stage calculation results; keep as many digits as is practical (at least one more digit than the rounding rule allows per stage) until the end of all the calculations to avoid cumulative rounding errors while tracking or recording the significant figures in each intermediate result. Then, round the final result, for example, to the fewest number of significant figures (for multiplication or division) or leftmost last significant digit position (for addition or subtraction) among the inputs in the final calculation.<ref>{{cite web |url= http://www.ligo.caltech.edu/~vsanni/ph3/SignificantFiguresAndMeasurements/SignificantFiguresAndMeasurements.pdf |archive-url= https://web.archive.org/web/20130618184216/http://www.ligo.caltech.edu/~vsanni/ph3/SignificantFiguresAndMeasurements/SignificantFiguresAndMeasurements.pdf |archive-date= June 18, 2013 |title= Measurements and Significant Figures (Draft) |first= Virgínio |last= de Oliveira Sannibale |year= 2001 |work= Freshman Physics Laboratory |publisher= California Institute of Technology, Physics Mathematics And Astronomy Division }}</ref>
