How to output an integer as a float number?

In C++, if we initialize 2 float variables as 4.0 and 4.0 and find their sum (float variable), it output's 8 and not 8.0. Why so? N how to make the output 8.0?

use setprecision(n) manipulator, where n is decimal precision. example float f =3.14159; cout <<setprecision(4) << f << '\n'; cout <<setprecision(9) << f << '\n'; Output: 3.1416 3.14159

Use float(sum) instead of sum at the time when you want to print. cout << float(sum); This is explicit type conversion.
