Total charge

Dear all.

I have done a very simple calculation that I have put a single H atom at the center of a 10X10X10 cubic cell and calculated with paw potential for H.in the INCAR file I gave LORBIT = 10 and I saw that in the OUTCAR the total Charge is 0.337 which is to me is absurd as for single H it should be around 1 electron.Am I right?
I changed RWIGS value and also I have done with a very fine K-Mesh and I have also tried with ISPIN=2,and lastly I have made the cell size 20X20X20, but in all the cases it was not near to 1.00 electrons.Can you explain it why?

1) single atoms have to be calculated with the Gamma point only
2) concerning the partial charges questions: this has been discussed in this forum several times , please read the corresponding postings & replies
