IMO, it does NOT require IEEE754 - it only requires numeric_limits<T>::digits to be correct for that type T.
So, it works for NTL quad_float which is NOT IEEE754.
That's what I was wishing to hear :-)

Hmm... what about "lexical_cast<> requires a good quality implementation"? ;-) Seriously, I'll take some time for writing good unit tests, so that we can have a clear view of what happens. This looks like a very sound addition to me. If it proves so in practice I guess Beman can add it to the standard proposal. -- [ Gennaro Prota, C++ developer for hire ]
