    Do I chop at the end or at every point that there is more than 4 digits after the decimal?

    Do you mean rounding, truncating, or determining significant figures?

    Sounds like you mean truncating then. Truncate = chop off.

    If 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.

    Example. 123.456789 truncated to four digits = 123.4 If you want to truncate to a particular place value, say, the ten-thousandths place, then 123.4567 is truncated at the fourth digit after the decimal point.

    Ah, only round or truncate at the very end of your calculations! That is very important.

    That is a matter of significant figures then. If you round or truncate in the middle of your calculations you'll get round-off error and all sorts of other nasty business.

    Check 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.
