# Point

Find whether the LED you say on the 
[LED screen](/device/screen) is on or off.

```sig
led.point(0,0);
```

### Parameters

* ``x`` is a [number](/reference/types/number) that means the
  horizontal spot on the LED screen (from left to right: 0, 1, 2, 3,
  or 4)
* ``y`` is a [number](/reference/types/number) that means the vertical
  spot on the LED screen (from top to bottom: 0, 1, 2, 3, or 4)

If a parameter is [out of bounds](/reference/out-of-bounds) (a value
other than 0 to 4), this function will return `false`.

### Returns

* a [boolean](/blocks/logic/boolean). If it is `true`, that means the LED is on. If it is `false`, that means the LED is off.

### ~hint

The LED screen is a solid square of LEDs with five LEDs on each side.
To learn more about how you number the LEDs with ``x`` and ``y``
coordinates, see [LED screen](/device/screen).

### Example: Toggle off

This program turns the center LED (2, 2) off if it is already on.  (If
it is already off, this program leaves it off.)

```blocks
if (led.point(2, 2)) {
    led.unplot(2, 2)
}
```
