Comment (by jdemeyer):
Replying to [comment:41 gagern]:
> Or, to put it differently, this is not about converting number field
elements. This is about converting the ''generator'' of a number field,
which itself is an algebraic number, into a symbolic expression. This
involves finding solutions of a symbolic polynomial, comparing isolating
intervals (which is a thing of algebraic numbers not number field
elements), and if that fails, casting to an algebraic number and comparing
the result for equality. Seems to me a lot closer to algebraic numbers
than to number field elements.
I'd say it's about number field elements with a specified embedding...
