For instance, a mean of n values has n times the precision of the individual values: roughly, include one extra significant figure for 3 ≤ n ≤ 30, two for 30 < n ≤ 300, etc. (This is rounding on a log-10 scale, obviously.) WebSo if the dividend has 3 significant digits and the divisor has 2 significant digits, for example, the quotient of the division operation can only have 2 significant digits in it. So, again, the quotient can only have as many significant digits as the least amount of significant digits … high bereavement risk
