Best Answer

The zero at the end is significant. It indicates that the number has been rounded to the nearest hundred thousandths: it lies between 0.004295 and 0.004305 whereas if it had two sig figs it would have been rounded to the nearest ten thousandths and lie in the range (0.00425, 0.00435).

All non-zero digits are considered significant. Trailing zeros in a number containing a decimal point are significant.
