It helps number round to nearest tenth, hundreds, thousands, & decimal places with sig figures rules. To prevent repeating figures that aren't significant, numbers are often rounded. In many contexts, trailing zeros are only displayed if they are significant: for instance, if a gauging that is precise to four decimal places (0.0001) were to be given as 12.23, then it would usually be mistaken to show that just the two of decimal places of precision are available according to the rules and formula of sig figs calculator.
