Sprite position in terms of tiles

[microspace]

Is there a way to determine sprite position in terms of tiles, faster than in the example: 

 update: function () {
      var cposx = Math.floor(player.x / TileSize);
      var cposy = Math.floor(player.y / TileSize);
}

I dont want to load too much calculations inside update function. Maybe there is asynchronous way to do this or maybe there is built-in function to od this.

Is it necessary to calculate position every frame? Maybe you could update players position only when he is actually moving, or even only once after the move ends. Besides, I do not think that such simple calculations could slow down game in any noticeable way.

No, I don't need to calculate position every frame, only once he crosses tile boundary.

Maybe you are right
