Ticket #9947 – Description
initial v1 1 In some cases GiNaC leaves `numeric` objects in the terms of an `add`: 2 1 3 {{{ 4 sage: a=(sqrt(4*(sqrt(3)  5)*(sqrt(3) + 5) + 48) + 4*sqrt(3))/ (sqrt(3) + 5) 2 5 sage: a.imag() 3 6 sin(1/2*arctan2(0, 88* + 1))*sqrt(abs(4*(sqrt(3)  5)*(sqrt(3) + 5) + 1)) 4 7 }}} 5 8 See the output of the second argument of {{{arctan2}}}. 9 10 The term `88*` is generated by the `expair` `22*4`. This term should be moved to the overall coefficient. 11 6 12 See also #9913.
