these two publications should explain it:

https://www.frontiersin.org/journals/artificial-intelligence/articles/10.3389/frai.2023.1144886/full
 
going wider with DNNs for higher accuracy. let me know if you have more questions.

Huge integers I can understand (because sometimes you need results that
are not just precise but exact), but what's the use for float1024?
float256 would already have enough precision to represent measure the
size of the observable universe at Planck length precision.

I'm not saying there isn't a use for such a type, but I'm genuinely
curious as to what that use is.
