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.
1.239 rounded to 3 significant digits is 1.24
There are three significant digits in 60.1.
35164 is 35200 rounded to 3 significant figures. To round to 3 sig fig, use the 4th digit to decide whether to round up or down; digits after the first 3 are replaced by zeros: 4th digit is 6, so round up 35164 → 35200 to 3 sig fig.
Three. All nonzero digits are significant and zeros in between significant digits are always significant.
3 significant figures.

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).
There are three rules that are used when rounding to a desired number of significant digits (figures): 1. All digits that are not zero, are significant 2. In a number that does not have a decimal point, all zeros between two non-zero digits are significant digits 3. In a number that has a decimal point, all zeros after the leftmost non-zero digit are significant Examples: 12345 rounded to 3 significant digits: 12300, or 1.23 x 104 12.345 rounded to 3 significant digits: 12.3, or 1.23 x 101 0.012345 rounded to 3 significant digits: 0.0123, or 1.23 x 10-2 0.012045 rounded to 3 significant digits: 0.0120, or 1.20 x 10-2 In the last example the zero after 2 is significant. That is the reason for keeping it in the result when rewriting it in powers of 10 notation.
