# attoseconds

The number of attoseconds represented by this `Duration`.

```
var attoseconds: Int128 { get }
```

## Discussion

This property provides direct access to the underlying number of attoseconds
that the current `Duration` represents.

```
let d = Duration.seconds(1)
print(d.attoseconds) // 1_000_000_000_000_000_000
```
