Hi Jason, OK, thank you very much, it's clear, now I understand the performance explanation when doing 'CDF(i^2)', sage in this case does not perform a simplification before coercing to CDF, clearly (for performance reasons), the key is the represantation of "i^2" as -1, so may this is not good ? :-) should a symbolic expression not be represented how it is internally?
but anyway, thanks again, I completly understand now (at least I think so :-)) Georg --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
