Hello,
I would like to understand why the following works
sage: K1.<s1> = NumberField(x^3 - 2, 's1', embedding=RR(1.26))
sage: RIF(s1)
1.259921049894873?
and the following does not
sage: K2.<s2> =NumberField(x^3 - 2, 's2', embedding=CC(-0.63,1.09))
sage: CIF(s2)
Traceback (most recent call last)
...
TypeError: unable to coerce to a ComplexIntervalFieldElement
Thank you, Vincent
I do not know when it was fixed, but It seems to be fixed now:
sage: K2.<s2> =NumberField(x^3 - 2, 's2', embedding=CC(-0.63,1.09))
sage: CIF(s2)
-0.6299605249474365? + 1.091123635971722?*I
I have been getting bugs from time to time as well. There are times when Sagemath can't even call out digits of pi for me. I have to close out the program, and browser that does fix the issues most of the time, but not all the time.

Looks like a bug to me. `CIF.coerce_map_from(K2)` shows that a sane conversion *should* happen, but then something goes wrong when actually coercing an element.
Ok. Thanks. I sent a message on sage-devel and sage-nt.
