Yes Paul, In the case of comparison on Quantity you have to consider units. There are no units on decimal.

One thing to be aware of is that not only will the RDF need to harvest the fractionDigits from the number of decimal digits in the instance, it will also need to examine the units, in the case of a Quantity or derivative, to harvest the exponent, if any, and apply that to the decimal value so that reasoners have the fully expressed value. For example a pseudo xml: <Instance_A> <value = "1.0200"/> <units = "10^4 ml/min"/> </Instance_A> <Instance_B> <value = "1.0200"/> <units = "10^3 ml/min"/> </Instance_B> The precision of the above examples are the same, but the values are different.
