# fractionCompleted

The fraction of the overall work that the progress object completes, including work from its suboperations.

```
var fractionCompleted: Double { get }
```

## Discussion

If the receiver object doesn’t have any suboperations, [`fractionCompleted`](/documentation/Foundation/Progress/fractionCompleted) is generally the result of dividing [`completedUnitCount`](/documentation/Foundation/Progress/completedUnitCount) by [`totalUnitCount`](/documentation/Foundation/Progress/totalUnitCount). Setting both [`totalUnitCount`](/documentation/Foundation/Progress/totalUnitCount) and [`completedUnitCount`](/documentation/Foundation/Progress/completedUnitCount) properties to zero indicates that there is no progress to track. In this case, the [`isIndeterminate`](/documentation/Foundation/Progress/isIndeterminate) property returns <doc://com.apple.documentation/documentation/Swift/false> and the [`fractionCompleted`](/documentation/Foundation/Progress/fractionCompleted) property returns `0.0`.

If the receiver does have suboperations, [`fractionCompleted`](/documentation/Foundation/Progress/fractionCompleted) reflects progress from those progress objects in addition to its own [`completedUnitCount`](/documentation/Foundation/Progress/completedUnitCount). When the suboperations finish, the [`completedUnitCount`](/documentation/Foundation/Progress/completedUnitCount) of the containing progress object updates.
