Thanks. Yeah, it turns out that's what I've done in the past. This issue seems to keep catching me as I expect fixed point arithmetic and a lot of my latitude/longitude calculations end up being exact (e.g. 180 div 2.5).
Why not use a fixed point library rather than convert to xs:double ? I don't expect xs:decimal to be efficient--just exact.
