+23254 Significant digits do not depend upon the location of the decimal point; the significant digits are 1535.
When you are rounding to 3 significant digits, look at the fourth digit (in this case, the last 5). If this digit is 5 or more, round up the third digit; if this digit is smaller than 5, leave the third digit alone. In both cases, drop the fourth digit, and any that are after it.
So, round 0.01535 to 0.0154.
