      Returns:
        instantiated Number object

    - #### public static Number parseInteger(String text)

      Builds a Number from the given integer descriptor. Creates the narrowest type possible, or a specific type, if specified.

      throws:
        NumberFormatException if the number does not fit within the type requested by the type specifier suffix (invalid numbers don't make it here)
      Parameters:
        `text` - literal text to parse
      Returns:
        instantiated Number object
