Datasets sometimes define their numeric data incorrectly at the term level. There is an important distinction between decimal numbers (including integers) and floating-point numbers. Both are defined in XML Schema 1.1: Datatypes. It is especially common to represent decimal numeric data using floating-point numbers.
This query gives an overview of the properties that are likely to using floating-point numbers to represent decimal numeric data.
This is done by automatically converting each double (
xsd:double) to an integer (
xsd:integer), and back to a double again. If no information was lost, the double could have been modeled as an integer.
