The imaginary unit of Python's complex numbers displays
(and is input) as 1j.
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 r
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 wor
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!
