The first 3 significant digits of a number are the first 3 digits starting from the left ignoring any leading zeros. So 31456 = 31500 (3 significant digits) The 5 in the "56" rounds the 4 up.
14.587020 rounded to four significant digits is 14.59
2.005
14.587020 has eight significant digits. If you were going to round it off to four, the answer would be 14.59
The answer depends on the number of significant digits that you wish to round to.

When multiplying numbers with different numbers of significant digits, the result should have the same number of significant digits as the least precise measurement. Count the number of significant digits in each number, perform the multiplication as usual, and then round the result to the least number of significant digits used in the calculation.
No, counting numbers you can ignore or say they have an infinate number of significant digits. By counting numbers I mean things you count, or non measurements, or numbers you wouldn't round to significant digits anyway . Measurements always have significant digits.
You can just round it off. For example, if your number is 8.38572998472654400131... that is equal to approximately 8.4 (if two significant digits is enough for your purposes) or 8.39 (if you prefer 3 significant digits).
Well, in science you always need significant digits: 0 has no significant digits, so we round to the nearest number with 1 significant digit: namely, -1 or 1.
The answer depends on the number of decimal places or the number of significant digits to which you wish to round the number.

=ROUND(Number, Number of Digits) Number is the number you are trying to round. Number of Digits is the amount of digits you want to round it to. So for example: =ROUND(41.98662,3) That will give you 41.987 as the answer.
