It *is* documented(section 4.1.3.3 "Float Operators", Relational 
expressions), but I don't think this is what he is looking for. I think 
Marc-Hendrik is looking for a not operator for isosurface functions. 
Such an operator does not exist as far as I know, it might be a better 
idea to just try CSG...though you could also do it by fiddling around 
with the functions to get their "inside" on the other side of the 
surface.
