Hi Lorenzo,
the strange behaviour of round() is explained in the documentation:
sage: u.round?
...
This method evaluates an expression in "RR" first and rounds the
result. This may lead to misleading results.
sage: RR(u).round()

sage: RealField(100)(u).rou

We actually have a doctest confirming that it's awful =)
This would probably be an easy project.

Hi everyone, first time sage user here.
I am puzzled by the behavior of round():
sage: t=sqrt(4320373582484102551677386613153502)
sage: floor(t)
65729548777426599
sage: round(t) #everything as expected, floor ≤ round ≤ ceil
65729548777426600
sage: ceil(t)
65729548777426600
sage: u = sqrt(43203735
