Yes, and then
sage: a.n()
yields a Traceback,
TypeError: unable to simplify to complex approximation
More precisely, it is about approximating the error function (which
admittedly I don't know...) if the argument is not real:
sage: erf(pi).n()
0.999991123853632
sage: erf(I).n()
Traceback (most recent call last):
...
TypeError: unable to simplify to complex approximation
Cheers,
