Whe I do a polarization calc, I get numbers that don't seem to add up:

Polarization in cartesian coordinates (C/m^2):
(the sum of the electronic and ionic Berry phase has been fold into [-1, 1])
Electronic berry phase: 0.183E+00 -0.155E-17 0.215E+00
Ionic: -0.157E+00 0.737E-15 -0.196E+00
Total: -0.171E+00 0.778E-15 0.495E-01

for example, (leaving out the expectation values which are 0):

in the x-dir: 0.183+(-0.157) does not equal -0.171.

1. does this have something to do with the fold?
2. when submitting a paper to an journal, should i just report the total figure?

tnx,
