3. If, in your application, it is enough to know whether the given object x is equal to an integer, then you could do "x in ZZ". Note that this property has nothing to do with the type!
CONCLUSION: We already have four different meanings of the question "Is x an integer?". Since different meanings of the question require different answers, there is certainly not *one* single test for "bein an integer" in Sage.
Well. I didn't think to that. Thanks very much for your answer. I take the third solution :) In my case, I just want to make the difference between numbers like pi/2 and 90 in order to guess if the user is thinking about degrees or radian.
