The java.text.DecimalFormat.format(double d) treats -0.0 as the positive number.
But following the principles of float and double type -0.0 and +0.0 are the 
different numbers and should be processed in the differnt ways. Javadoc should 
clarify it.

Here is the test demonstrating the bug:

-----------------TestD.java------------------------
import java.text.*;
import java.util.*;


public class TestD {

    public static void main (String args[]){
        DecimalFormat df = new DecimalFormat("#,##0.0##");
        df.setDecimalFormatSymbols(new DecimalFormatSymbols(Locale.ENGLISH));
        double d1 = -0.0;
        double d2 = -0.0001;
        StringBuffer f1 = df.format(d1, new StringBuffer(), new FieldPosition(0));
        StringBuffer f2 = df.format(d2, new StringBuffer(), new FieldPosition(0));
        if ( !f1.equals("-0.0") || !f2.equals("-0.0")) {
          System.out.println("Test failed");
          System.out.println("pattern: \"" + df.toPattern() + "\"");
          System.out.println(d1 + "      is formatted as " + f1);
          System.out.println(d2 + "      is formatted as " + f2);
          System.out.println("This numbers should be formatted as -0.0");
        } else {
          System.out.println("Test passed");
        }
    }
} 
---------Output from the test---------------------
Test failed
pattern: "#,##0.0##"
-0.0      is formatted as 0.0
-1.0E-4      is formatted as 0.0
This numbers should be formatted as -0.0
