#2910 In maxima 5.35.1 powerseries fail if there complex root

[Silvestre Paredes Hernandez]

Hi:

There is a bug in powerseries function, can anybody fix it?

CORRECT:
In Maxima 5.34.1
     (%i): niceindices(powerseries(1/(z+%i),z,0))
     (%o): -%i*sum((-1)^(m/2)*z^m,m,0,inf)

WRONG:
In Maxima 5.35.1
    (%i): niceindices(powerseries(1/(z+%i),z,0))
    (%o): sign: argument cannot be imaginary; found

Bye.
Silvestre.
