Hi,

I want do difference two functions (to add a third one afterwards) and thing
it could be done by "& not". Alas, I can't find the logical "not" operator
in functions. Do I miss something? Does a simple "& -" the job or is there
no logical "not"?
I can't use "sign -1" because that would effect the hole function.

Thanks in advance,

Marc-Hendrik
