C++ string to double and vice versa

The C++ 11 way is to use std::stod and std::to_string. Both work in Visual Studio 11.

The STL offers the desired functionality: std::string s = "0.6" std::wstring ws = "0.7" double d = std::stod(s); double dw = std::stod(ws); http://stackoverflow.com/questions/1012571/stdstring-to-float-or-double
