float precision

[vassilisw]

When a float is dumped and becomes float again via json::parse, looses precision

    json jjj;
    jjj["f"] = 11.123456789;
    float f = json::parse(jjj.dump())["f"];
    std::cout << f << std::endl;

expected: 11.12345678..
getting: 11.1235

Is there any way to increase precision?

Yes, increase your output precision:

std::cout.precision(12);
std::cout << f << std::endl;
