I prefer to ask the question here before because the presence of the tests

Hello.
I play a little with Sympy Gamma and I think that it would be better to
not show sympy commands by default.
It should be better to decide to hide them and to have the possibility
to show sympy commands if we want it.
Just a suggestion. ;-)

If I use *S(1)/4* or *1./4*, all works as expected.
I have understood that is normal because 1/4 is an euclidean division.

Does Sympy supports something like Decimal("1.234") of the standard module

On the other hand, Sympy should print something like Float("1.234", 10) so
as to say to the user that a float with a mantisse of 10 digits is used.

There is a difference between a decimal, ie a rational which can be written

Python 3. This is very usefull.
Is there just one dmg for SymPy ? If not, maybe the setup in the source
codes of NumPy and matplotlib could help to build such a dmg for SymPy.
Best regards.

Hello,
is there someone on this list that knows a good book reference about the
Karr summation algorithm ?

On the other hand, we also have to heard that the elementwise multipication
is often used.
The most important thing will be to have a good choice.

ion can use something like ° that could be
better because it is near from the dot scalar of two vectors. *I do not
think that @ is really intuitive. *
A math user of Sympy, Numpy and Scipy that will note appreciate to use @

z-plane must be changed to xy-plane. Sorry for this.

Hello.
In your prototype, you have written :
b.arbitrary_point('z') = Point(-13*z +5, -11*z+5, -8z+5)
c=Line(Point(2,3), Point(3,5)) # Here the default value of z is taken as 0
Why don't you work with a symbolic variable z ?
You will also have to take care of point in segment for example.

Thanks for this two answers.

ot; should be treated as a complex. By
giving an integer id for the kind of a number, and by choosing integer_id <
rational_id < reals_id < imaginary_id < complexe_id, then the kind of
number could be the maximum of all the id met in an expression.
What do you think about that ?
Christop
Hello.
Is there an equivalent of FullForm that produces simple treeview of a
formula ? Here is basic example seen in a video.
FullForm[x**2+x**3] = Plus[Power[x, 2], Power[y, 3]]
Best regards.

Hello.
Can you give a little example showing how to define an infix operator in

Hello,
as a simple user, I think the support of conic and quadratic is also needed
for 2D and 3D geometry.
There is also a need to allow a way to put a 2D context into the 3D one.
