The coolest part is you can do log math since you have the mantissa and exponent already for extremely fast multiplication and division (+ or - log values)
Fast inverse square root go brrrr.
Just store the fraction as a varchar like “11/17”, duh
Is that done in some environments? I think Maxima gives answers as fractions by default, but didn’t know how that worked. And my Casio calculator can stick to fractions and surds up to a point, but I think it’s just using float under the surface and converting back ok until too much rounding error creeps in…
I’ve written econmerce systems and to avoid floating point errors I’d just use ints and divide by 100 on the front end.

It’s likely based on the theory of continued fractions and the calculator has a limit to the maximum denominator allowed to return an approximation of the fraction.
