I now have a real rationale to promote a change in
the way complex numbers with small imaginary part are displayed.
I agree with you.
I would add

If Windows users want to test the patch, I have prepared a Windows build

The patch also fixes this.
So, very small numbers are reduced to strict 0...
This is a bad implementation of the variable format mode. The Scilab 5
one was correct, at least on this point.

Yes, but there is an "infinite" amount of decimal numbers
that cannot be stored exactly in IEEE754.

tored value is different from the displayed value.
The first thing that you can see is that the default format(10) would
be very verbose, but this is tunable. A value of 7 would be ok, but
quite low for format("e").
