when I try to take logarithms of a complex number sage version 3.5
doesn't like it. How do I find/use a multiplication preserving
embedding to make it work?

Perhaps working in the symbolic ring is causing something you don't
like. In David's example above, you might want to convert things to
CDF, which gives:
sage: a = CDF(1 + 3*I)
sage: z = log(a)
sage: z
1.1512925465 + 1.2490457724*I
...instead of
sage: a = 1 + 3*I
sage: z = log(a)
sage: z
Ahmed,
Looks good, but I am creating a function in python that is called.
And 1r, .56r ,etc. does not pass. I am taking these parameters from a
form and then using the function.
Is there a work-a-round?
Thanks

Kevin,
It worked.
Thanks, a lot.

Maybe you can use:

or, explicitly define the number type when calling the scipy function.
Good luck,

you won't have the pre-processor issues, so I may be misunderstanding
what your underlying problem is.
Assuming you are in Sage (since this is a Sage mailing list) and
calling Scipy, other options that achieve the same effect

Let me give some more details about my question: i have a number field
K, and a ring of polynomials over it, R1. I also have a ring
homomorphism from K to QQbar (which actually makes all sense from a
mathematical point of view), and a ring of polynomials R2 over QQbar.
All this should give a map
Yes, I am calling Scipy functions from a standard Python, thus no
preparser. It does not recognize 1r, 10r, etc.
Is there anyway to get it to work? I have also tried R, but r.binom
does not work.
