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

Why not use BigDecimal

BigDecimal a = new BigDecimal("10.126");
BigDecimal floored = a.setScale(2, BigDecimal.ROUND_DOWN);  //  == 10.12
