- When the answer to a calculation contains too many significant figures, it must be rounded off. There are 10 digits that can occur in the last decimal place in a calculation. One way of rounding off involves underestimating the answer for five of these digits (0, 1, 2, 3, and 4) and overestimating the answer for the other five (5, 6, 7, 8, and 9).

- What I'd like is a method to convert a double to a string which rounds using the half-up method. I.e. if the decimal to be rounded is a 5, it always rounds up the previous number. This is the standard method of rounding most people expect in most situations.I also would like only significant digits to be displayed.loating-point doesn't have decimal places so you cannot possibly round/truncate to a specific number of them in the first place. You have to work in a decimal radix, and that is what those two classes do.

Significant Digits and Rounding To write a large number in scientific notation, move the decimal point to the left until it is between the first and second significant digits; the number of places moved is the exponent. For example, 167 becomes 1.67, but the decimal point moved two places left. Therefore 167 = 1.67×102 or 1.67E2.

Rounding Numbers In general, you round to a given place by looking at the digit one place to the right of the target place. If the digit is a five or greater, you round the target digit up by one. Otherwise, you leave the target as it is. Then you replace any digits to the right with zeroes (if they are to the left of the decimal point) or else you delete the digits (if they are past the decimal point).
