There are two things found in iomanip that must be included. First is fixed and the second is setprecision

You need to write:

std::cout << fixed;  
std::cout << setprecision(2) << f;

fixed disables the scientific notation i.e. 1.23e+006 and fixed is a sticky manipulator so you need to disable it if you want to revert back to scientific notation.

Use - 

cout.setf(ios::fixed, ios::floatfield);
cout.setf(ios::showpoint);

before printing out the floating point numbers.

More information can be found here.

You can also set output precision with the following statement - 

cout.precision(2);

or simply with - 

printf("%.2f", myfloat);
