WebWhen rounding off numbers to a certain number of significant figures, do so to the nearest value. example: Round to 3 significant figures: 2.3467 x 10 4 (Answer: 2.35 x 10 4) example: Round to 2 significant figures: 1.612 x 10 3 (Answer: 1.6 x 10 3) What happens if there is a 5? There is an arbitrary rule: If the number before the 5 is odd ... WebThe rules for tracking significant figures in logarithm calculations (such as ln or log) are simple, but how you count the digits is a little different. Remember from previously that only the digits in the mantissa of a logarithm are significant – the digits after the decimal: . The same rules apply to “natural logarathims” (ln) as to base-10 logs:
