declare(antisymmetric)

[smaslovski]

Hi,

On current maxima 5.39.0 on Android:

(%i1) display2d: false;

(%o1) false
(%i2) declare(mult,antisymmetric);

(%o2) done
(%i3) mult(a,b)+mult(b,a);

(%o3) 2*mult(a,b)

This problem seem to exist only in Maxima on Android. You can find more details in the related thread on maxima mailing list.

As was found on Maxima mailing list, this is most likely due to a compiler bug, because the results for the compiled and not compiled functions differ.
