# floorsDescended

The approximate number of floors descended by walking.

```
var floorsDescended: NSNumber? { get }
```

## Discussion

This value reflects only the floors descended while the user was walking or running down stairs and does not reflect the floors descended by elevator or other assisted means. A single floor has a height of approximately three meters. The value in this property is `nil` when floor counting is not supported on the current device.
