Rational Number Module about swift-numerics HOT 2 OPEN

Thank you so much for your response @stephentyrone. I see what you mean about the use cases and limitations. I will write up a a list of use cases with their justifications and limitations(I may need some help noticing them).

I'll be back in a jiffy!

Hi @kieranb662, thanks!

Can you give some examples of the use cases you have in mind for this module? Broadly speaking, my experience is that fixed-width rational numbers (i.e rational numbers that use a fixed-size integer type for the numerator and denominator) are not very useful, because most non-trivial computations will overflow the denominator after a few operations, and computations that don't suffer from that problem involve numbers that all share a common unit scaling, so scaled-integer or floating-point would always be a better option.

I'm not opposed to adding a rational type, but to get this started I'd like to see less implementation and more justification.
