I see; actually I didn't test it in an older version of Maxima since I only had 5.34.0 installed. Maybe it is because of #16224 instead? This fixed a bug in the Maxima interface that changed (among other things) which Sage function corresponds to Maxima's abs(). Anyway, a bit more experimenting shows that this behaviour can be fixed using "declare(x, complex)": (%i1) display2d: false; (%o1) false (%i2) abs(sqrt(x)); (%o2) sqrt(x) (%i3) declare(x, complex); (%o3) done (%i4) abs(sqrt(x)); (%o4) abs(sqrt(x)) (%i5) abs(1/sqrt(x)); (%o5) abs(1/sqrt(x)) Peter -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
