Hello Arkady,

> But I wrote *why* you need that :

We are talking about two different "why"-s here ... I know that I have to
do the calculation according to the specification, otherwise it will not
work. I have no problem in understanding that.

My question is why that particular type of calculation was choosen ( in
specific, why that calculation uses one value twice).


Curently I feel like arguing with a police officer :

Me : Why do I have to follow that rule ?
Officer : Otherwise you get a ticket
Me : No, I mean : will not following it endanger me or others or something ?
Officer : No, because otherwise you will get a ticket.
Me : ?????????

Although the answer is correct, it does not answer the question : no reason
to the why of the rule is given, only a reason why not to break it ....

Regards,
Rudy Wieser
