[QE-users] Polarization calculation using nscf

[Amar Singh]

Hi,
My NSCF calculation on BaTiO3 resulted in a polarization value in o/p file as "P =  -0.2274527  (mod   0.5081493)  C/m^2" along {001} direction. 

How should I read this? Is the polarization 0.22 C/m^2? What is this number 0.508? 

Thanks 
Amar
