Hi, Vaclav!

It definitely solved the problem. I do not know, why Mathr did not work
there:

There are 2 conditions, which were in shop.cpp:

> if (Mathr::FAbs(b->cn) <= Mathr::ZERO_TOLERANCE ) b->cn=0;
> if (Mathr::FAbs(b->cs) <= Mathr::ZERO_TOLERANCE ) b->cs=0;
>

The comic thing is, that the FAbs(b->c*n*) worked normally, but FAbs(b->c*s*)
did not!!!
I can't find the explanation of this issue.

You think it is a good idea to get rid off "Mathr" everywhere, where
possible?
