Rule 1: In numbers that do not contain zeros, all the digits are significant. 3.1428 [5] 3.14 [3] 469 [3] Rule 2: All zeros between significant digits are significant 7.053 [4] 7053 [4] 302 [3] Rule 3: Zeros to the left of the first nonzero digit serve only to fix the position of the decimal point and are not significant 0.0056 [2] 0.0789 [3] 0.000001 [1] Rule 4: In a number with digits to the right of a decimal point, zeros to the right of the last nonzero digit are significant 43 [2] 43.0 [3] 43.00 [4] 0.00200 [3] 0.40050 [5] Rule 5: In a number that has no decimal point, and that ends in zeros (such as 3600), the zeros at the end may or may not be significant (it is ambiguous). To avoid ambiguity express the number in scientific notation showing in the coefficient the number of significant digits.
