Interestingly, in the session where I originaly started with, I now get ... (see below). Isn't that weird?
Unfortunately, I cannot reproduce what actually caused that different behaviour for the same thing.
Oh... the modifying behaviour comes from
%%% (20) -> digits 1000
After that, I also get a non-zero expression for
imag(x4)
Very weird.
