wrong printing of the result of negation of NaN values

Name: ###@###.### Date: 09/05/96

the result of negation NaN values is printed as -NaN instead
             of NaN

Tests: execution of the following test:

public class test
{
public static void main(String argv[])
{
System.out.println(- Float.NaN);
System.out.println(- Double.NaN);
}
}

produced such output:

-NaN
-NaN

instead of expected:

NaN
NaN
