Thanks for your response.
The two areas that I had particular interest in were representing groups
symbolically as you mentioned, and also potentially looking into generating
Galois Groups. Do you think these would be good areas to start with?
Obviously there is a huge amount that could be done
So perhaps you would have better results if you started with a Float
with higher precision, like Float(0.07071, 100).

Hi,
I'm Isuru Fernando. I'm a 3rd year Computer Science and Engineering
undergraduate at University of Moratuwa.
I've been working on CSymPy for some time now and would like to work on the
Sage GSoC project to use CSymPy as the symbolic engine.
I have a couple of questions regarding the
A much reduced testcase:
x,y = [Symbol(_) for _ in ['x','y']]
foo = 1/(x+y)-Rational(1,2)*x**2
print(foo.apart(x))
This prints:
1/(x + y)
If the Rational has an integral value, everything looks ok:
foo = 1/(x+y)-Rational(6)*x**2
print(foo.apart(x))
Output: -6*x**2 + 1/(x + y)

It looks like a bug. If you do foo.expand() - foo.apart(xi_s).expand()
you get a term which is definitely not equal to zero.

Hello list,
I feel a bit embarrassed as probably I am doing something blatantly wrong,
but I cannot understand what is going here. Consider this snippet (copy
pasted from an Ipython notebook):
import sympy
sympy.init_printing()
from sympy import Symbol,sqrt,cos,sin,solve,Function,atan,apart,S
Those both sound like good ideas. I would look into what the
prerequisites for each are so you can see what is already implemented
and what needs to be implemented.

Heh. I agree with rather no docs than bad docs.

I believe the purpose of this class was to make it easier to remove
the assumptions from the core. I would dig into the pull request and
commits that introduced it to see if there is more information. I
agree it's weird to have BasicMeta be both the metaclass and the
superclass.

I suppose it must be there to distinguish subtypes from other subtypes
of BasicMeta that aren't BasicType. Either that or it used to have
methods but they were deleted, and the class was not deleted. I would
look into the git history of it using git blame.

Class BasicType defines no methods or attributes, its only subclass is
BasicMeta.
Neither class is in the sympy namespace.
Does BasicType serve any purpose that BasicMeta would not?
