I think this is what you want

  GIGA_SIZE =3D 1073741824.0
  MEGA_SIZE =3D 1048576.0
  KILO_SIZE =3D 1024.0

  # Return the file size with a readable style.
  def readable_file_size(size, precision)
    case
      when size =3D=3D 1 : "1 Byte"
      when size < KILO_SIZE : "%d Bytes" % size
      when size < MEGA_SIZE : "%.#{precision}f KB" % (size / KILO_SIZE)
      when size < GIGA_SIZE : "%.#{precision}f MB" % (size / MEGA_SIZE)
      else "%.#{precision}f GB" % (size / GIGA_SIZE)
    end
  end
