# setFloatValue(_:toParameter:at:)

Sets the value of a floating point parameter.

```
func setFloatValue(_ value: Double, toParameter parameterID: UInt32, at time: CMTime) -> Bool
```

## Parameters

`value`

Specified value for the parameter.

`parameterID`

Unique identifier for the parameter.

`time`

Specified time to set the value.

## Return Value

Returns `YES` if the value is set successfully; `NO` otherwise.

## Discussion

When used to set the value of an angle parameter, the result will be expressed in counter-clockwise degrees. 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](/documentation/Professional-Video-Applications/understanding-time-in-fxplug).
