Gilles Sadowski commented on NUMBERS-77:
----------------------------------------

{quote}
{code}
default double signum(double a) {
    return (a == 0.0 || compare(a, 0.0) == 0 || Double.isNaN(a)) ? a : 
Math.copySign(1.0, a);
}
{code}
{quote}

I think that there is a problem when {{0 < |a| < eps}}.
