The following code raised a runtime error:
R = RealField(500)
print(erfc(R(28.0)))
Output:
/home/sc_serv/sage/local/lib/python3.7/site-packages/sage/rings/real_mpfr.pyx in sage.rings.real_mpfr.RealNumber.erfc (build/cythonized/sage/rings/real_mpfr.c:31648)()
5047 """
5048 cdef RealNumber x = self._new()
-> 5049 sig_on()
5050 mpfr_erfc(x.value, self.value, (<RealField_class>self._parent).rnd)
5051 sig_off()
RuntimeError: Aborted
However, it would work if the RealField is removed:
print(erfc(28.0))
Output:
6.56321584032878e-343
Is there a way to make erfc work also for arbitrary precision real fields?
