you can vary precision in a "degree encoding" scheme as well just truncating rightmost bits, that's precisely why I referenced using fixed point and not floatin

you can vary precision in a "degree encoding" scheme as well just truncating rightmost bits, that's precisely why I referenced using fixed point and not floating. it also makes extra convenient to transform them into base32 and maintain some of the property that the scheme has (small changes in coordinate result in small changes in the encoded sequence etc)
