From this ask answer, we have:

sage: RealIntervalField(200)(Ei(1))
1.8951178163559367554665209343316342690170605817327075916462273?

sage: RealIntervalField(200)(Ei(-1))
-0.21938393439552027367716377546012164903104729340690820757797849?

But:

sage: RealBallField(200)(Ei(1))
RecursionError: maximum recursion depth exceeded

sage: RealBallField(200)(Ei(-1))
RecursionError: maximum recursion depth exceeded
