Hi Robert, thanks for your fast answer, just one more question, > RDF and RealField(35) are canonically isomorphic,
what does that mean exactly, as far is I know, sage uses the 'gsl' for computations with 'RDF', and computations with 'RR' are done through 'mpfr', so if I write for example 'sqrt(5. + RDF(5))' and 'sqrt(RDF(5) + 5.)', does sage rely on the correctnes of both implementations of sqrt (one from gsl, one from mpfr) to be comutative? thanks, Georg --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
