ok, so I am surprised :) Therefore I back off ;)

but honestly - there must be a bug somewhere (I belive it's in
lexical_cast), right? Maybe authors of lexical_cast should add one
significant place to the string? If not - then why this won't work? Is
it really impossible to avoid losing data in conversions?

best if one of boost::lexical_cast authors would answer....
