# value

The value of the dynamic parameter.

## Declaration

```swift
var value: Float { get set }
```

## Discussion

Discussion The range of possible values varies between different parameters. For example, the dynamic parameter for haptic intensity ranges from 0 and 1, indicating a multiplicative envelope, whereas the dynamic parameter for haptic sharpness varies between -1 and 1, indicating that the parameter can additively increase or decrease the sharpness.
