Alexey is right. But I can create an exception that derives from
bad_lexical_cast, for example bad_lexical_cast_overflow. However it is
a huge amount of work (it requires implementation of all float types
casts in lexical_cast library without streams and C libraries usage
and rewriting about 1k of code lines). I`ll keep in mind your
proposal, but it won't be implemented in nearest releases.
