| 0 | Use printf command. Using printf you can decide the number of floating point digits.
printf ("floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416);
%f means: Print a floating point number.
%4.2f means: Print the floating point number (the first number after the double quotation) totally in for space. and 2 digits after the floating point.
In our case you should use
printf ("%0.1f", res);
Then it will print res with 1 digit after the floating point. It says 0 there that means the total space is not important print the number as it's with one digit after the floating point.

| 1 | sorry,
float precision is not enough, it's better to use "double".
