Best ResponseYou've already chosen the best response.0Do I chop at the end or at every point that there is more than 4 digits after the decimal?

Best ResponseYou've already chosen the best response.1Do you mean rounding, truncating, or determining significant figures?

Best ResponseYou've already chosen the best response.1Sounds like you mean truncating then. Truncate = chop off.

Best ResponseYou've already chosen the best response.1If you want your answer to only have 4 digits, then count four digits starting from the left, keep those four and get rid of all the rest.

Best ResponseYou've already chosen the best response.1Example. 123.456789 truncated to four digits = 123.4 If you want to truncate to a particular place value, say, the tenthousandths place, then 123.4567 is truncated at the fourth digit after the decimal point.

Best ResponseYou've already chosen the best response.0yes but my question is as follows like do u chop off like at any point while u r solving or only once u have solved the whole equation?

Best ResponseYou've already chosen the best response.1Ah, only round or truncate at the very end of your calculations! That is very important.

Best ResponseYou've already chosen the best response.1That is a matter of significant figures then. If you round or truncate in the middle of your calculations you'll get roundoff error and all sorts of other nasty business.

Best ResponseYou've already chosen the best response.1Check this example: 12.34567 times 2.98765 = 36.88454098... Truncated at the fourth digit is 36.88 But if you 'chop' first then, 12.34 times 2.987 = 36.85958, which would be chopped to 36.85. That is off from the correct answer by 3/100.
