Issue with coordinate and /setblock command.

The jist of the bug is that when using the /setblock command such as "/setblock 5 4 5 1" instead of placing the block and x=5 y=4 z=5 it would place it one more off so it'd be X=6 y=4 z=5.

I was using command blocks to make a door and when i activate the command block I expected it to place it directly at the coordinate.

What actually happened was the block was placed over by one block.

Steps to Reproduce:
1. place command block
2. enter command /setblock x y z "block"
3. activate command block
4. observe coordinates in the command block and where the block is actually placed.

As some additional information when i was looking into this i noticed that there is a coordinate for X, Y, and Z, that are all -0 which there is no negative zero when it comes to numbers or coordinates. So i suspect that that is the source of the problem.
