Hah, I *almost* tried that on a hunch, but then wasn't able to build a mental model where casting to a string would ever be 
productive (when the end goal is a floating point value).  Just goes to show you that sometimes it's probably better to think less 
and stick with the hunch.  :-]

Thanks very much for the detailed info and explanation,
