How to handle division of a very small numerator? – Blancer.com Tutorials and projects

I’m developing a JavaScript calculator and facing an issue with the division operation. When very small numerators are divided by large denominators, the result becomes “0”. This isn’t the desired behavior. Ideally, the calculator should either:

Display a more informative message (e.g., “Number too small to divide”).

        const result = 1.2e-321 / 99999999999999;
        console.log(result);
    </script>
</body>
