I agree, and the text is less than ideal in several other places.
But I don't especially like your phrase 'infinite range', even
though the idea is right. I think the necessary terminology
already exists. How about something like this?
There are interfaces (defined in header R_ext/Applic.h) for definite
("proper") and for _improper_ integrals, improper meaning that at
least one of the limits of integration is infinite.
Moving ahead, I would use Definite and Improper for "Finite:" and
"Indefinite:".
