Comment (by Chromatix <mhazadmanesh2009@…>):

 As my comments in the example code show, converting to string or char* is
 always OK. Problem arises when you want to ''convert the string
 representation of the error into a floating point type'' (say, double).
 For example trying to lexical_cast the above result ("-nan" in GCC,
 "-1.#IND" in MSVC) to a double throws bad_lexical_cast instead of
 returning a double containing that special value.
