We actually have a doctest confirming that it's awful =)
This would probably be an easy project.
Definition: u.round(self)
Source:
def round(self):
"""
Round this expression to the nearest integer.
This method evaluates an expression in ``RR`` first and rounds
the result. This may lead to misleading results.
EXAMPLES::
sage: t = sqrt(Integer('1'*1000)).round(); t
3333333333333333056287287783757109595393...
This is off by a huge margin::
sage: (Integer('1'*1000) - t^2).ndigits()
984
"""
#FIXME: can we do better?
