See my previous report:
http://thread.gmane.org/gmane.comp.lib.boost.user/23644
which continues at
http://thread.gmane.org/gmane.comp.lib.boost.user/23664
The conclusion at that time was that
- you can just cast to an int if this is what you want.
- you shouldn't be using bytes to store numbers - that's unnecessary
size optimisation.
I didn't agree with those conclusions, and I'm no longer using boost::format.
Phil.
