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.

|  The "fix" is wrong. It broke the "else if" statemen at line 
|  150 and my gcc 
|  (4.0.2-SuSE) complains about "boost/lexical_cast.hpp:150: 
|  warning: statement 
|  has no effect".
|  
|  I propose the following patch.
|  
|  Yours,
