Point being "there is a whole article talking about the possible definitions, intricacies and exceptions" saying it is undefined is a perfectly fine definition - especially for an advanced CAS system.

Sorry Tim, I'm not going to read any article which try to "prove" obvious nonsense, as here that 1/0=inf.

As mentioned already, in special cases/theory it may be perfectly correct, however that does not mean it should be generalized on plain real numbers, which is absolute nonsense.

I would like to see teacher who explain to students why 1/0 is infinity, since a calculator return such result...
