I'm having a physics lab in which a report needs to be submitted after an experiment. The experiment includes many measurements: values with their errors. I need to round the error up to 2 significant digits, and then to round the value up to to the amount of digits that the error is presented. For example: * The measurement [tex]123.4567 \pm 0.489583[/tex] will be rounded to [tex]123.46 \pm 0.49[/tex] * The measurement [tex]123.4567 \pm 1.006[/tex] will be rounded to [tex]123.0 \pm 1.0[/tex] Instead of doing this manually, I thought to myself that probably someone already wrote a formula for Excel that will accomplish this, while considering all possible/problematic situations (unique scenarios). So this is my attempt at finding the formula.. did you wrote a formula like that? Or could you please refer me to a place that has it? Thank you..
