It seems that printing of complex numbers has changed. With maxima 5.23post, I get: (%i1) -1-2*%i; (%o1) - 2 %i - 1 With the current git version, I get -(2 %i) - 1 Was this change intentional? I kind of like the old way better. (I'd much prefer -1 - 2*%i, but that seems much harder to produce.) Ray
