Hello Qian,
I just checked, since some of your work it is now possible to use the
Windows nightly build, I better understand. Having a self installer
was more destined for official releases because Windows users,
usually, expect an installer and a way via "add/remove programs" to
cleanly delete
Hello Waldek,
Exactly what I was looking for. Thanks.
I thought only integer based indexing was allowed, and since Record is
a FriCAS primitive I thought indexing by Symbol, or whatever, was not
possible.

For a given fn of type FileName I cannot simply say
fh := open(fn, "output")
if the folder directory(fn) does not yet exist.
I haven't found any other way than using
systemCommand("system mkdir -p " directory fn)$MoreSystemCommands
. Is there a more OS-independent way to create a

We are looking at sign of argument to a radical.
OK, so for radicals, there should be a much more effective
method to determine its sign. Seems like current method is
mostly focused on polynomials and pretty limited for radicals.

Yes. Othewise there is problem with
You said before AlgebraicNumber should represent any branch
of the root, but here we are talking about the sign of radical.
Does that mean we are taking a specific branch interpretation here?

Thank you, Waldek,
that explains the behaviour much better. I suspected that there must be
some numerics involved, but when I had put debugging output near places
where I saw Float-s, that never appeared, so I got a bit confused and
didn't want to waste more time on this.
Potentially, I
