Thanks Vincent!What version of Sage are you using? With sage-9.8 I get:
---
from sympy import sympify
exp = sympify("CRootOf(x**5 + x + 1, 0)")
sage_poly = QQ['x'](list(map(QQ, reversed(exp.poly.rep.rep
sage_approx = RIF(exp.n()) + RIF(-1e-30, 1e-30)
QQbar.polynomial_root(sage_poly,
Dear Marcel,
It is a pity that this does not work more directly. Here is a work around
to achieve what you want to do
sage: exp = sympify("CRootOf(x**5 + x + 1, 0)")
sage: sage_poly = QQ['x'](list(map(QQ, reversed(exp.poly.rep.rep
sage: sage_approx = RIF(exp.n()) + RIF(-1e-30, 1e-30)
sage:
