# Percentage of Actors

> Enable features for a percentage of actors.

Consistently on or off for this user as long as percentage increases. Think slow rollout of a new feature to a percentage of things.

###### Percentage of Actors Example

```ruby
user = User.find(...) # responds to flipper_id method call

Flipper.enable_percentage_of_actors(:new_design, 25)

# returns true or false consistently for the same enabled percentage and actor
Flipper.enabled?(:new_design, user)
```

Percentage of actors also takes into account the feature name to ensure that the same actors are not granted access first to every feature.

> **Note**
> 100% of actors will not return true if no actor is provided.

```ruby
user = User.find(...) # responds to flipper_id method call

# turn on for all actors
Flipper.enable_percentage_of_actors(:new_design, 100)

# true because 100% and actor is passed
Flipper.enabled?(:new_design, user) # true

# false because no actor provided
Flipper.enabled?(:new_design) # => false
Flipper.enabled?(:new_design, nil) # => false
```
