java.text.DecimalFormat.format incorrectly formats -0.0

Name: dfC67450 Date: 01/26/98



java.text.DecimalFormat.format(double, StringBuffer, FieldPosition) formats -0.0
as +-0 if positivePrefix set to "+".
 
Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;

public class Test {
    public static void main (String args[]){
        DecimalFormat df = new DecimalFormat();
        df.setPositivePrefix("+");
        double d = -0.0;
        System.out.println("pattern: \"" + df.toPattern() + "\"");
        System.out.println(d + " is formatted as " +
                df.format(d, new StringBuffer(), new FieldPosition(0)));
    }
}


---------Output from the test---------------------
pattern: "+#,##0.###;-#,##0.###"
-0.0 is formatted as +-0
