I'd like an entity that creates the fraction 3/16. I have the ISO table of fractions, but it does not include a 3/16. So . . . 1. Can I, by emulating the declaration structure of the ISO table, "trick" it into creating a new fraction? 2. What damage does that do to the whole notion of ISO Standards? Elizabeth H.
