>>> from sympy import Symbol, oo, simplify
>>> x = Symbol('x', real=True)
>>> simplify( x*oo )
oo*x
Do we use extended real number system(Affinely Extended Real Number System)
in sympy ?
If we do use them, then why not expressions like these "x*oo" evaluated to
a Piecewise function like
>>> Symbol('x')
>>> simplify( x*oo )
Piecewise( ( -oo, x< 0 ), ( oo, x > 0), (Nan, x==0 )) # i expect this
to happen.
