# getFloatValue(_:fromParameter:at:)

Gets a floating point value from a parameter.

## Declaration

```swift
func getFloatValue(_ value: UnsafeMutablePointer<Double>, fromParameter parameterID: UInt32, at time: CMTime) -> Bool
```

## Parameters

- `value`: Pointer to the plug-in variable for the value.
- `parameterID`: Unique identifier for the parameter.
- `time`: Specified time to get the value.

## Return Value

Return Value Returns YES if the value is retrieved successfully; NO otherwise.

## Discussion

Discussion When used to get the value of an angle parameter, the result will be expressed in counter-clockwise radians. Depending on the host application, the time value may be relative to the start of the timeline or to the start of the clip. See Understanding time in FxPlug.
