I would argue against this. Global modes are in general something I think should be avoided, and especially for something like this (imagine if something used sin in its plot method, would it have to be mode aware? Something that uses sin to do fourier transformations internally?) Also, would the derivatives, simplifications, etc. have to respect radian vs. degree mode? If we add support for this, I would vote that it be part of a units package (like inches, liters, etc.) rather than a mode. I would be much more comfortable with having to type sin(degree_to_radian(45)) # not sure if this is worth the namespace pollution or even sin(45 degrees) # would require the preparser than setting a mode. - Robert --~--~---------~--~----~------------~-------~--~----~ 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-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
