To avert repetitive figures that are not significant, you can round the given number. Significant figures definitions. There are three digits in the number 3.14 that are significant because each digit is non-zero. Manage Settings We can do this by employing significant figures. 2. Suppose we want 3,453,528 to 4 significant figures. When fulfilling significant numbers of the standard rounding rules are valid, except that zeros replace non-state numbers on the left side of the decimal system. (0.012 has 2 sig figs) If there is a decimal point, then, according to rule (3) explained above, any trailing zeroes are considered to be significant figures. Although you have a volume of fluids that seems accurate to the thousandths, you have to round to the ones place because that is the least significant place value. Often, leading zeroes or trailing zeroes can be removed and the number remains just as accurate (004 means the same as 4, for example).
