Formatting a double and not rounding off

Question

I need to format (and not round off) a double to 2 decimal places.

I tried with:

String s1 = \"10.126\";
Double f1 = Double.pa         


        

Answer 1

Have you tried RoundingMode.FLOOR?

String s1 = "10.126";
Double f1 = Double.parseDouble(s1);
DecimalFormat df = new DecimalFormat(".00");
df.setRoundingMode(RoundingMode.FLOOR);

System.out.println("f1"+df.format(f1));
