[Bug classpath/23466] New: Double.toString(0.0010) ---> "0.001" ISO "0.0010"

[veldema at cs dot fau dot de]

Tried with gcj 4/3.4 and own compiler with classpath from CVS:
Double.toString() gives wrong answer for some inputs.
Example:
--------------[input]----------
class hi {
    static double a = 0.0010;
    public static void main(String args[]) {
        System.out.println("hi:" + a);
    }
}
-----------[outputs]--------------
address@hidden:~/tests> javac hi.java
address@hidden:~/tests> java hi
hi:0.0010
address@hidden:~/tests> gcj hi.java --main=hi
address@hidden:~/tests> ./a.out
hi:0.001

-----------[ problem ]-----------------
The problematic code is in _dtoa somewhere.
Also, shouldn't the call to _dtoa be:

  _dtoa (value, 0, (isFloat ? 20 : 1), &decpt, &sign, NULL, buffer, (int) 
isFloat);

???
