If you want, you can create a macro to give your current position.

For example:

/script posX=0; posY=0
/script posX,posY=GetPlayerMapPosition("player")
/script posX=floor(posX*10000) / 100
/script posY=floor(posY*10000) / 100
/script DEFAULT_CHAT_FRAME:AddMessage(format("[ %s ] %.2f , %.2f",GetZoneText(),posX,posY));

If I've typed it correctly, this one will give your current zone and coordinates (I decided to round it to 2 decimal places, but change the last like to whatever you feel like).

Sometimes it behaves funny and gives me 0.00, 0.00 (usually if I just toggle my map on and off, it behaves properly again).

I'm sure there are better and more concise macros out there, but this should do for now.  :)
