Sometimes n() returns a symbolic expression: ---------------------------------------------------------------------- | Sage Version 4.5.3, Release Date: 2010-09-04 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: a=(sqrt(4*(sqrt(3) - 5)*(sqrt(3) + 5) + 48) + 4*sqrt(3))/ (sqrt(3) + 5) sage: a.imag().n() 0.939469338708203*sin(0.500000000000000*pi)
The expected output would, of course, be 0.939469338708203 Regards, /Håkan Granath -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
