Section 6.2 Member Functions and Precision

A function that is associated with a certain type of object is called a member function of that object. You have already used member functions setf(...) and precision(...) for formatting our output streams using cout. These functions are included briefly below:
// Use cout's member function "set flags", called setf
// The argument here means to use a fixed point rather than scientific notation
cout.setf(ios::fixed);

// Use cout's setf function again, but this time
// The argument tells cout to show the decimal point
cout.setf(ios::showpoint);

// Use cout's member function, called Precision
// The argument indicated to display 2 digits of precision
cout.precision(2);
