True or False??

If done properly true,
however sometimes people over round figures as they are only after approximate figures, so the actual result may be much more accurate, e.g. the practice of using 3.14 for pi.
Also others sometimes put in too many decimal places as the result of a calulation, e.g. if I have a square piece of paper that is 10.1 cm long +/-0.5cm the stating that the area is 102.01 cm squared would be too accurate and should probably be rounded to 102 to keep 3 significant figures.Keeping the extra decimal places could be misleading.
