Blizzard builds the coordinates into the game but gives no easy, obvious way to access them without a mod; however, mods are not *needed* for this. Try this script command:
/script px,py=GetPlayerMapPosition("player")
DEFAULT_CHAT_FRAME:AddMessage(format("[ %s ] %s , %s",GetZoneText(),(px*100 ),(py*100)));
/script px,py=GetPlayerMapPosition("player")
DEFAULT_CHAT_FRAME:AddMessage(format("[ %s ] %s , %s",GetZoneText(),(px*100 ),(py*100)));
