The request 'num-rational' names no specific product, so the answer lists tools for exact rational arithmetic. Arithym offers exact fraction arithmetic and exact square roots of rationals via its action tools 111, and SymPy provides symbolic/exact math 6. mpmath 3 and SciPy 5 are arbitrary-precision or numerical libraries, but their sources do not show exact rational arithmetic, so they are not listed.
