    fl_numerator = 1

    fl_denominator = 3

    And division is a "stretch goal" once we get funding.

    Do you have a computer type that can represent the entire rational set?

    Yes. Have a structure with 2 BigInts. Treat one as the numerator. The other as denominators.

    It might not be efficient or fast. But it is possible.

    No. They all need to mimic certain numbers.

    So, you have a notation that can represent the entire rational set?

    What exactly is being mimicked?
