5796	"Casting from float to string using ""lexical_cast<string>"" gives inaccurate values."	Mikko Partonen <mikkopartonen@…>	nasonov	"When casting floats to strings with lexical_cast<string>() for use in wxTextCtrl, the new boost versions adds a lot of nines or zeroes along with some random numbers at the end of the float values.
For example, with an older boost version, I get ""0.96"" and ""0.8"" and with new versions, I get ""0.959999979"" and ""0.800000012"".

I believe this new feature has to do with this problem:

""The previous version of lexical_cast used the default stream precision for reading and writing floating-point numbers. For numerics that have a corresponding specialization of std::numeric_limits, the current version now chooses a precision to match.""

This can easily be fixed by using an older version of lexical_cast.hpp file. Wouldn't it be better to fix this issue, so that I wouldn't need to use the old version of lexical_cast.hpp?

I attached the lexical_cast.hpp version with which conversions from floats to strings works."	Bugs	closed	To Be Determined	lexical_cast	Boost 1.47.0	Cosmetic	wontfix	lexical_cast, float	antoshkka@…
