More generally in my opinion n() in complex domain needs improvement For example (as I have mentioned) sage: ((-1)^(1/3)).n() 0.500000000000000 + 0.866025403784439*I leads to wrong solution sage: s=solve(3*x^3-9*x+10,x,solution_dict=True) sage: ns=[n(s[k][x]) for k in range(3)] sage: ns [1.06780542232902 - 1.84949324407141*I, 0.0277635108030695 + 1.24902476648341*I, -1.09556893313209 + 0.600468477588001*I] # no real solution, no conjugate solutions Andrzej Chrzeszczyk -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
