What is CCAccelerometer meaning of the value of z.

Hi!
I tried to find CCAccelerometer information.
i can’t find meaning of CCAccelerometer variables (x,y,z).

Just i can find only example of TestCpp.

That example is just used CCAccelerometer variables (x,y)
so i assumed that i think x is roll rotation, y is pitch rotation.

i don’t know value of z, so i measure that.

So I think that x and y values is the roll, pitch.
but I can’t find meaning of the value of z.

In general, i think z is yaw rotation.

please let me know what CCAccelerometer value of z.
