Actually, according to Dictionary.com (I don't have my proper paper dictionary with me) round can be a transitive verb, an intransitive verb, a noun, an adjective, OR a preposition. Craziness. But anyway:

"adv.
1. In a circular progression or movement; around.
2. With revolutions: wheels moving round.
3. To a specific place or person: called round for the pastor; sent round for the veterinarian. "

The only one I would PERSONALLY use would be the 3rd, but I think, again, that that is just a function of the area in which I learned English. I bet "round" as an adverb is much more common in other areas.
