Webfixed and setprecision are both manipulators in C++ that control the output formatting of floating-point values. fixed is used to set the floating-point output format to fixed-point notation, which means that the decimal point is always present and the number of digits after the decimal point is fixed. WebIn order for setprecision( ) to accomplish this task, you will have to set an ios flag. The flag is set with the following statement: cout.setf(ios::fixed); Once the flag has been set, the number you pass to setprecision( ) is the number of decimal places you want displayed. The following code: cout.setf(ios::fixed);
