Hello Users,

is thre any functions in the std::string  which converts strings into correspondent numbers?

I mean "123.40" = double 123.40

Many thanks.
GC.
 		 	   		  

You should use string streams:

#include <sstream>
  std::string strNumber = "23.4";  std::cout << "strNumber = " << strNumber << std::endl;
  std::stringstream ss;  ss << strNumber;  double dNumber;  ss >> dNumber;  std::cout << "dNumber = " << dNumber << std::endl;

Thanks,

David
