I disagree that this answer is "wrong". If you want a mathematically correct answer you are going to have to obtain it by applying intelligence to the algorithm in which this calculation occurred. This is not a mailing list about numerical methods in general, so it probably isn't appropriate to pursue that conversation here. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
