Description (last modified by burcin)
In some cases GiNaC leaves numeric objects in the terms of an add:
sage: a=(sqrt(4*(sqrt(3) - 5)*(sqrt(3) + 5) + 48) + 4*sqrt(3))/ (sqrt(3) + 5) sage: a.imag() sin(1/2*arctan2(0, -88* + 1))*sqrt(abs(4*(sqrt(3) - 5)*(sqrt(3) + 5) + 1))
See the output of the second argument of arctan2.
The term -88* is generated by the expair -22*4. This term should be moved to the overall coefficient.
See also #9913.
