Formatting double

Question

I need to format a double value without any precision
It can have 13 digits to the left of decimal and 6 digits right side of decimal.
I used
     public static String formatDouble(double dNumber) {
          DecimalFormat dcf = new DecimalFormat("##################0.000000");
          String sformattedDouble = dcf.format(dNumber);
          return sformattedDouble;
Now the problem is that the DecimalFormat class uses ROUND_HALF_EVEN rounding, which I do not want to use.Should I be using some other data type(like BigDecimal) instead as the numbers I am dealing with are pertaining to currency values so I can not use precision ?
Any suggestion will be great.

Answer 1

Sorry I meant.....I do not want it to be rounded off
e.g. If I use it in following way I get
999999999999.000000 as output
     public static void main(String args[]) {
          double dbl = 999 999 999 998.999 999;
          System.out.println(formatDouble(dbl));
You are trying to place a number with 18 decimal places in a double which only hold about 17 decimal places so the conversion to 999999999999 get done before you try to use it. If you realy need this sort of precision then you could try BigDecimal but be prepared for a big performance penalty.
