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: float_test.rb
    path of file: ./repos/universalid/test/universalid/message_pack_types/scalars
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class UniversalID::Packer::FloatTest < Minitest::Test
  def test_pack_unpack
    expected = 789.456
    packed = Uni
    
  def test_build_parse_decode
    expected = 789.456
    uri = URI::UID.build(expected).to_s
    uid = URI::UID.parse(uri)
    actual = uid.decode

    assert uri.start_with?("uid://universalid/CwSAy0CIq6XjU_fPAw")
    assert_equal expected, actual
  end
