An OWL version of such an ontology would be a "good thing."  Discussions
a while back on these lists, revealed that the XML derived semantics for
integers and floats in RDF are not what is wanted for such engineering uses
such as measured values.  Developing an open-source OWL-based engineering
math ontology is also a timely idea as there has recently been talk of some 
of the high profile promoters of the semantic web directly supporting an 
open-source ontology registry/repository.

For Semantic Web styled models in this area, have a look at David Leal's work 
on an RDF(S) vocacabulary for quantities and units[1].  This reuses work that 
was done as part of the ISO STEP standardization effort to support information 
exchange of (manufactured) product data.  CIM/XML[2] may also include models 
for units and measured values, although again these would be in RDFS.  CIM
is a power industry standard and their control systems associate somewhat richer
metadata with measured values.
