When it is between non-zero digits, e.g.: 504 or 2005When there is one or more zeros after the last non-zero digit AFTER the decimal point, e.g.: 3.40

When there are zeros after the last non-zero digit in a whole number, one or more zeros MAY be significant, e.g.: 500. But if you have to guess, you should consider such zeros to be non-significant.
