WebThe rule is: If the zero has a non-zero digit anywhere to its left, then the zero is significant, otherwise it is not. For example 5.00 has 3 significant figures; the number 0.0005 has only one significant figure, and 1.0005 has 5 significant figures. A number like 300 is not well defined. Rather one should write 3 x 10 2, one significant ... Webrelative uncertainty precision x fractional uncertainty best = x = = σ To avoid confusion with fractional uncertainty, the uncertainty is sometimes called the absolute uncertainty.
