Hello!

The example for boost::numeric_cast contains documentation, which clearly is wrong and stumbles the reader.

On

http://boost.org/libs/numeric/conversion/doc/numeric_cast.html#numeric_cast

we have the lines

unsigned long l=std::numeric_limits<unsigned long>::max(); // This works, because unsigned integral types cannot cause overflow. unsigned char c=numeric_cast<unsigned char>(l);

which contradict the behaviour and the range checking logic presented on

http://boost.org/libs/numeric/conversion/doc/converter.html#rchklogic

Btw.: Further on the #include directive, namely

#include <boost/numeric_cast.hpp>

should be corrected to

#include <boost/numeric/conversion/cast.hpp>
