Let me clarify my earlier post, with a nod to Mike Raiford's clue.  I can
see now why there's a bit of confusion. POV's description is correct,
though "worded" in mathematical terms.


Say that A = 32.

abs(A) will then produce A, which is 32.

Now, say A  = -32.

abs(A) will then, according to the POV doc, produce -A.  Which is - (-32).
Which is again 32.

Voila!
