It seems that there is a possible ambiguity in the number of significant digits if there are trailing 0's, but no decimal point or overline or underline. Specifically, I am looking at the definition of the second, which the Halliday & Resnick book has listed as(adsbygoogle = window.adsbygoogle || []).push({});

9 192 631 770

So is this 9 or 10 digits? Should it be presumed that an integer with trailing 0's, but without the decimal point, overline or underline has those 0's as significant or not?
