Given an integer, returns a "reasonable" IntFormat instance to represent
        any number between 0 and n if n > 0, -n and n if n < 0

        Parameters
        ----------
        n : int
            max number one wants to be able to represent
        min : int
            minimum number of characters to use for the format

        Returns
        -------
        res : IntFormat
            IntFormat instance with reasonable (see Notes) computed width

        Notes
        -----
        Reasonable should be understood as the minimal string length necessary
        without losing precision. For example, IntFormat.from_number(1) will
        return an IntFormat instance of width 2, so that any 0 and 1 may be
        represented as 1-character strings without loss of information.
