boost::lexical_cast is a Boost function to convert to/from std::string to/from (possibly) any data type. CanLexicalCast can check if this conversion is possible.

The C++11 equivalent to convert to a std::string is std::to_string.


#include <string>

#include <boost/lexical_cast.hpp>



int main()

{

  const std::string s = "12.34";

  const double d = boost::lexical_cast<double>(s);

}

LexicalCast serves the same purpose as boost::lexical_cast, but does not use Boost and does not throw an exception when conversion fails. Note that there are differences between LexicalCast and boost::lexical_cast, as boost::lexical_cast is more strict.
