Yes. See 'fixed', 'setprecision' and other I/O manipulators (the
header <iomanip>).

Look up stream manipulators (in header <iomanip>) in your favorite C++
reference book.

#include <ios>
#include <iomanip>
#include <iostream>

int main()
{
double d(0);
d = 1.0 / 3.0;

std::cout << std::fixed << std::setprecision(7)
<< d << '\n';

return 0;
}

Output:

0.3333333
