6953	Cannot serialialize some double values	dbaciu@…	Robert Ramey	"Hi,

The code sample below throws a ""stream error"" exception at line

ia >> double_back;

My development environment is Visual Studio 10, boost version 1.43. Sorry, I have not tried a newer version of boost.

The binary archive does not seem to handle doubles with lots of decimal places.

#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>



void dummy()
	{
        
		string filename = ""dummy.data"";

		double someDouble = 0.98123024735605502;
	
		{
			std::ofstream ofs;
			ofs.open(filename.c_str());
			boost::archive::binary_oarchive oa(ofs);
			oa << someDouble;
		}
			
		double double_back;
		{
			std::ifstream ifs;
			ifs.open(filename.c_str());
			boost::archive::binary_iarchive ia(ifs);
                        // following throws a ""stream error"" exception
			ia >> double_back;
		}

	}

Thanks,

Dragos
