The Unix "man" page for atan2 has some information. It's not as
detailed as the Ada manual, because after all this is C and providing
specific details would infringe on the inalienable right of C
programmers to shoot themselves in the foot. However, the man page
I'm looking at does say:
(1) that the result is between -pi and pi (inclusive), and
(2) the signs of both arguments are used to determine the quadrant of
the result.
So I'd guess that the semantics are probably the same.
