Hi, I'm using sage 3.1.3 on Debian system. Is this a bug or a feature? sage: type(5. + RDF(5)); type(RDF(5) + 5.) <type 'sage.rings.real_mpfr.RealNumber'> <type 'sage.rings.real_double.RealDoubleElement'>
somehow '+' ist not comutative, allthough '5. + RDF(5) == RDF(5) + 5.' yields 'True', and sage: type(RDF(pi) * 5.n(prec=53)) <type 'sage.rings.real_double.RealDoubleElement'> sage: type(5.n(prec=53) * RDF(pi)) <type 'sage.rings.real_mpfr.RealNumber'> sage: type(5.n(prec=54) * RDF(pi)) <type 'sage.rings.real_double.RealDoubleElement'> especially the last one, should'nt that be coerced to a mpfr type of 53 Bit precision or is there a rule like coerce to the type with lower precision and if both are of same precision coerce to the first one? 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 -~----------~----~----~----~------~----~------~--~---
