Question: query "undefined" specifics

when a term in the evaluation of some calculus functions particularly, i sometimes arrive at output in the general form as follows:


Algebraic expression + undefined


i am just wondering if there is a function i can call that will return the specific details as to what error the term "undefined" placeholder has stored im assuming such information is held, ie is it undefined as a consequence of the limits either side not being equal to one another or is it a 0/0 evaluation.

Please Wait...
