    sscanf. Use the %f type specifer. Be sure to look at the example.
    I think you can also do it with a stringstream or something but I'm not sure how.

    Code:
    double num = 5.6e+4;
    std::cout << std::fixed << num << std::endl;

    If thats an output of an equation you have you could also do this. I had the same problem for my program.
    Code:
        cout.setf(ios::fixed);
        cout.setf(ios::showpoint);
        cout.precision(1);
    Change precision accordingly, the 1 would mean like 56000.0, 2 would be 56000.00 etc.

    Hope this helps.
