I encountered the following bug:
sage: abs(pi*I)
I*pi
The correct answer would have been pi.
Several other examples show a different behaviour, e.g.
sage: abs(log(2)*I)
abs(I*log(2))
Here, the answer is correct (but not particularly helpful, log(2)
would have been better).
I do not know whether this is related to
http://trac.sagemath.org/sage_trac/ticket/7557
System information: I am using
ftp://ftp.sun.ac.za/pub/mirrors/www.sagemath.org/linux/64bit/sage-4.6.1-linux-64bit-ubuntu_8.04.4_lts-x86_64-Linux.tar.gz
on debian lenny.
