Java keep trailing 0 in float operations

Question

the code:

Float f = Float.parseFloat(\"1.80\");
System.out.println(f);

prints \"1.8\" on screen. I need to keep the 0 in the float

Answer 1

You are confusing a number value and its formatting. It is not possible to actually store 1.80 as a float, however it is possible to display the number as a formatted String which forces two decimal places. Your options are:

1. Keep the original String that the user entered, if the number of decimal places they gave
   matters

2. Store the number as a float, but when displaying the number force it to display with two decimal places like this:

   System.out.printf("%.2f\n", f);
