Comment(by kcrisman):
Right now, there doesn't seem to be a lot of distinction in Sage between
unsigned and signed infinity, though of course as you point out there
should be. From sage.rings.infinity.py:
{{{
Note: the shorthand oo is predefined in Sage to be the same as
+Infinity in the infinity ring. It is considered equal to, but not
the same as Infinity in the UnsignedInfinityRing::
sage: oo
+Infinity
sage: oo is InfinityRing.0
True
sage: oo is UnsignedInfinityRing.0
False
sage: oo == UnsignedInfinityRing.0
True
}}}
There is unsigned_infinity, but the following seems problematic:
{{{
sage: unsigned_infinity
Infinity
sage: Infinity
+Infinity
}}}
What the heck?
