You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: features.rb
    path of file: ./repos/gitlabhq/lib/api
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module API
  class Features < ::API::Base
    before { authenticated_as_admin! }

    features_tags = %w[features]

    feature_category :feature_flags
    urgency :low

    BadValueError = Class.new(StandardError)

    # TODO: remove these helpers with feature flag set_feature_fla
    
      def gate_value(params)
        case params[:value]
        when 'true'
          true
        when '0', 'false'
          false
        else
          raise BadValueError unless params[:value].match? /^\d+(\.\d+)?$/

          # https://github.com/jnunemaker/flipper/blob/master/lib/flipper/typecast.rb#L47
          if params[:value].to_s.include?('.')
            params[:value].to_f
          else
            params[:value].to_i
          end
