Oops, looks like I made a hasty generalization.  I looked more closely, 
and the hexadecimal floating-point errors were all related to formatting 
them with string.format and "%a" or "%A".  Parsing them works okay.

(It looks like support for "%a" and "%A" in printf, etc., wasn't added 
until Visual C++ 2005.)

Thanks.
