And can we get relative to random

Relative to a random coordinate on the world?

If so, I have trouble finding uses for this in most cases, As the Y Coordinate would be a problematic wildcard for most random events.

I'm not sure, will have to check. In theory to the exact point 10 metres away, but it's possible the teleport code itself (outside the script) might adjust that to the block center.

If used with commands that require a whole number (Ex. Anything that manipulates blocks) Will it round up, Down, Or simply to the nearest whole number for the destination coordinate?
