Test the following source code:

//----------------------------
import java.lang.*;

public class test2 {

  public static void main(String[] argv) {
    double counter;
    counter=Double.parseDouble(argv[0]);
    double factor=0.000001;
    
    System.out.println("test:"+Double.toString(counter*factor));
    
  }
}
// --------------------------------------


after compiling call this program with 'java test2 5'
the result should be: 5.0E-6 but it isn't. it is: 4.9999999999999996E-6.
Something like this happens for all values which are integer multiples of 5.
 5-> 4.9999999999999996E-6
10-> 9.9999999999999998E-6
15-> 1.4444444444444449E-5
20-> 1.9999999999999998E-5
...

Calling the program with other integers, for example 4, produces the expected
output: '4.0E-6'.
The problem stays the same with negative values. With zero (0) everything is
okay.

I tested the program on a Compaq Armada 1592DT running RedHat Linux 6.2 and on a
Windows 98 Pentium III 650 MHz with JRE1.3 running on both systems.
