public static double value(double x)
```
    This implementation computes erfc(x) using the regularized gamma function, following Erf, equation (3).
    
    The value returned is always between 0 and 2 (inclusive). If abs(x) > 40, then erf(x) is indistinguishable from either 0 or 2 at double precision, so the appropriate extreme value is returned.
    
    Parameters:
    
    x - Value.
    
    Returns:
    
    the complementary error function.
    
    Throws:
    
    java.lang.ArithmeticException - if the algorithm fails to converge.
