[FIXED] How to display 3 decimal points without round up?

Issue

I am making an app which need to display 3 decimal points i achieve this by NumberDecimal but the issue is if 4th digit is >5 then 3rd digit automatically increase. I want to show exact figure for ex :

Result           : 100.2356 
Output           : 100.236  // Applying NumberDecimal

Need this output : 100.235 // I need this output

This is my function :
public String setdecimal(float a) 
{
   NumberFormat formatter = new DecimalFormat("##.###");
   return formatter.format(a);

}

Solution

Use RoundingMode.FLOOR:

NumberFormat formatter = new DecimalFormat("##.###");
formatter.setRoundingMode(RoundingMode.FLOOR);

Depending on how you want to handle negative numbers, you could also use RoundingMode.DOWN, which rounds towards zero.
