Hi! Let R be a ring that is an F-vector space, for some field F. Let x,y be elements of R and c be an element of F.
If I understand correctly, in order to implement x/y, one should provide a single underscore method x._div_. But what should one provide for x/c? It seems that the default behaviour is to replace x/c by x*(~c), but for efficiency I don't want that c is inverted in F before letting it act on x. Moreover, in my use case, R is not an integral domain (thus, has no fraction field), and actually I don't want division in R at all. So, what do I need to do in order to make x/y NOT work (and fail with a TypeError)? In the above situation, is it recommended to override double underscore __div__? Then what about Py3? Would it then be needed to override __div__, __truediv__ and __floordiv__? Best regards, Simon -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
