It's worse: Since according to IEEE +0 is not equal to -0, atan2 is not a function!
Sorry, I meant to write: Since according to IEEE +0 *is* to be regarded as equal to -0, atan2 is not a function. (Because it gives different values for argument combinations -0, +0.)
From my point of view it is a function. Only == is not the finest equality possible (but the one which is more useful).
