So far there have been severalinteresting reactions regarding:
* behavior of the (u)int128 typein relation to built-insand standards,
* documentation queries,
* concerns/ideas that even more "big"types could potentially be useful.
I'm very interested in "big number"types. Yet I feel that enlargingthe scope of this thread to othertypes may probably better left forfuture threads.
I can reaffirm need for (u)int128,as recently as we've used it inongoing specification work today.
Thanks for the enriching discussionso far.

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.
