Re: [GiNaC-devel] [PATCH] {add, power}::eval(): convert terms into primitive polynomials when possible.

Hi, Alexei Sheplyakov schrieb:

The following transformations are done automagically now: (-x+y)*(x-y) -> -(x-y)^2 (3*x+y)/(6*x+2*y)^2 -> 1/4*(y+3*x)^(-1)

Please note: exam_series13() from check/exam_pseries.cpp fails due to this patch, because the expression 1/x*(-(1+x)/(1-x)) + (1+x)/x/(1-x) gets evaluated to zero.

thanks for the patch! I modified exam_series13() so that it doesn't use the new transformation. Regards, Jens
