The sequence of naughts (and no other numbers) following a decimal point in measurements or other mathematical representations.
When used in some standardized fashion, trailing zeros can provide more accurate information for smaller numerical units. For instance "3.000" indicates greater precision than "3.0" although the trailing zeros do not have any affect on the actual number represented. Industry standards may dictate different formats for trailing zeros to provide more precise numerical information for product attributes. It is important from a data governance standpoint to ensure that duplicate values with differing trailing zeros are not present in a data set.
