Ignore that. It was nonsense. A better statement: the completion (in
the sense of lattices) of the real numbers is (isomorphic to) the
doubly-extended real line. It's in this sense that +infinity and -
infinity can be considered limits.
I've no clue where your (Steven's) idea that 'all ordinals are surreal
numbers' came from. They're totally unrelated.
