# doubleValue

The value that indicates the current extent of the progress indicator.

## Declaration

```swift
var doubleValue: Double { get set }
```

## Discussion

Discussion By default, a determinate progress indicator goes from 0.0 to 100.0. If the progress bar has advanced halfway across the view, this value would be 50.0. An indeterminate progress indicator does not use this value.
