comment Exact versus numerical approximation of an integral
@J.M. Actually, I am trying to approximate an integral with a similar form but which has no explicit solution. This one is an example to figure out the accuracy of my approximation.

@J.M.: Thanks! Would would suggest something else to approximate my integral?

@J.M.: Can you please be a little bit more explicit about "if the 'infinite extent' portion of your integral behaves very much like exp(−x)"

comment In what situations is the integral equal to infinity?
Thank you very much for the update. I still need to think on it, but I am more and more convinced! Thank you!

What do you think of this? Suppose, for example, that p and q have the same support, (0, infinity). If q(x) --> 0 much more quickly than p(x) --> 0 then the integral is infinity. Thx

Thank you, that interpretation helps. However, let us assume that p is absolutely continuous with respect to q, meaning that the support of p is a subset of the support of q. So distribution p cannot produce values that distribution q can never do. However, I think it is not enough to ensure finite values...
