No, it is not used in number theory as such.
"integral" when applied
to numbers is an adjective, not a noun. You
apparently do not know the
common English terminology.
(1) integers: ... -2, -1, 0, 1, 2, ...
(2) positive integers: 1, 2, 3, 4, ...
(3) non-negative integers: 0, 1, 2, 3, ...
(4) natural numbers: either (2) or (3), depending on
the author.
(5) whole numbers: either (1), (2) or (3), depending
on the author.

i agree with those (5)...

although by some authors natural numbers means N (therefore the N ) and
so by some authors (4) = (5) = (3)

N is *always* the set of natural numbers (i.e. (4)), but whether it
includes 0 depends on the author.

however (1) and (2) have no discussion

and besides neilist talked about irration triangular numbers ...

And you talked about the "integrals"...

that makes no sence now does it ...

"integrals" makes no sense either.

and btw i dont blame anyone for not knowing about the rare used terms ...

Again, *where* is the term "integrals" used with the meaning you did
give?
