PRationalData is missing a lot of functionality

[kozross]

Unlike its Scott-encoded cousin, we're missing a bunch of functionality, such as PShow, PNum, and quite a few besides. We should really add these.

There also doesn't seem to be any direct way to make one, other than pconstanting a PlutusTx Rational, which also seems weirdly deficient.

it's because you shouldn't use it

You should probably convert it to PRational if you're using it, albeit there are times where you would want to use PRationalData. It's not a deliberate omission, but rather a deliberate deprioritisation.

I agree, hence it's low priority
