The imaginary unit of Python's complex numbers displays

I realized that you may be just looking for the Python complex type. To
get that you can do:
sage: j = complex(i)
sage: (3 + 4*j)^2
(-7+24j)
Here are some other options. The first involves using number field
arithmetic, so it may not be what you want (you can't use floating point
values in the
why not just use j, and tell sage that j^2=-1?
Depends on how much of Sage you
expect to understand this.
(the use of j is common in electrical engineering,
for those who have not encountered this before...)

Is this what you're looking for?
sage: z = ComplexNumber(1,2)
sage: z
1.00 + 2.00*I
sage: print z.str(istr='j')
1. + 2.*j
I don't think there's a global way to do this in Sage. I'm also not quite
sure which kind of complex number you're
Hello everybody,
Ín sage, how change complex number symbols:
i^2=-1, z=a+bi
Now I want
j^2=-1, z=a+bj
Thank you!
