Solved PlayerMoveEvent - decimal point precision

Current PlayerMoveEvent:

Code (Java):

@EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        if(event.getTo().getBlockX() == event.getFrom().getBlockX() && event.getTo().getBlockY() == event.getFrom().getBlockY() && event.getTo().getBlockZ() == event.getFrom().getBlockZ()) return;
        if(PreventMovementManager.contains(event.getPlayer())) {  
            Location loc = new Location(event.getFrom().getWorld(), event.getFrom().getBlockX(), (int) event.getFrom().getY(), event.getFrom().getZ(), event.getFrom().getYaw(), event.getFrom().getPitch());
            event.getPlayer().teleport(loc);
            return;
        }
    }

This is my current code with this line:

Code (Java):

if(event.getTo().getBlockX() == event.getFrom().getBlockX() && event.getTo().getBlockY() == event.getFrom().getBlockY() && event.getTo().getBlockZ() == event.getFrom().getBlockZ()) return;

This line makes the code only cancel the event if the player moved a block.

However, I have another piece of code that helps to teleport the player to the centre of a block,


and I instead want to make it so that the code cancels movement events if the player moves out of the centre point (~.5, ~.0, ~.5). How would I do this?

 

I eventually managed to accomplish this, thank you for all your responses!

 

I got the end point by doing basic calculation and just subtracting the two values like kingOf0 mentioned, then checked against the 0.45 - 0.55
