But this is STILL the WRONG formula for the number of digits!
It should be max_digits10.
stream.precision(2 + std::numeric_limits<Source>::digits * 301/1000);
PLEASE can we get at long last get this right so that floats can be serialized without losing a few bits.
I have not get a chance to study the subject yet but I wonder why don't you just set a precision to some huge number, say 32767 or INT_MAX?
I presume lexical_cast will be totally rewritten not too far in the future, to optimize some specific conversions, as also recently discussed. That's why I've tended to postpone issues about it. But if you really feel strongly about this specific problem (please, say "I do so swear" ;-)) I'll give it a thought.
I can merge things ;) Though I can't promise warnings free code in the first round of refactoring. -- Alexander Nasonov Project Manager at Akmosoft ( http://www.akmosoft.com ) Blog: http://nasonov.blogspot.com Email: $(FirstName) dot $(LastName) at gmail dot com
