0.004560 to two significant figures results in: 0.0046
0.000039 as you have to round it up. 3 and 8 are the significant figures but as you must round up, the answer becomes 0.000039.
To round 233.356 to 2 significant figures, you first identify the first two non-zero digits from the left, which are 2 and 3. The digit after the second significant figure is 3. Since 3 is greater than 5, you round up the last significant figure. Therefore, rounding 233.356 to 2 significant figures gives you 230.
To round 1,248,486 to four significant figures, you focus on the first four digits, which are 1, 2, 4, and 8. The digit following these is 4, which means you do not need to round up. Therefore, 1,248,486 rounded to four significant figures is 1,248,000.
It depends on how many significant digits you want to round it off to.
To round a number to 2 significant figures, you first need to look at the first two digits. In this case that is 3.5. The next step is to look at the third digit and assess if we need to round up. If the digit is 5, 6, 7, 8 or 9 you round up. Otherwise you leave the figures as they are (round down). In this case the third digit is 8, and so we do need to round up. Thus 3.582 rounded to 2 significant figures is 3.6
