Playing with Sage and Sympy I accidentally ran sage from the directory ~/.config/ipython/profile_sympy
and noticed that the "engine" of symbolic computation has changed:
type (1)
sympy.core.numbers.One
The same thing happens if from sage to execute:
from sympy import *
It is experimental feature? Will it grow? What are plans to integrate sympy and sage if they are?
Thank you and sorry for my English.
