I think I'm starting to understand... Is it that when you say to the 
hardware "add .5" the nearest value to .5 it thinks is 1 ?  I think I get it.
   Any chance I could look at the code for numeric_cast<> without going 
through CVS?
(Maybe I can figure out some assembler trick to, at least, not use a branch.)
