double d = 5.5057787190877361e-001;
cout << setprecision(15) << fixed << d <<endl;

this prints 0.550577871908774

and instead of printing it, i need to save this value "0.550577871908774"

what i should to do ?

This is not related with OpenCV. Have a look into a C++ book.

#include <fstream>

// write to file:
ofstream o("bla.txt");
double d = 5.5057787190877361e-001;
o << setprecision(15) << fixed << d <<endl;


// read back:
ifstream i("bla.txt");
double d;
i >> d;
