tanshu 669821a643 Using Half-Round-Even rounding in the bill amounts as this is what python round uses. 
When the bill amounts were Odd number + .5, payment could not be received as javascript rounded it up, but python rounded it down.
We are now using the python rounding (Half Round Even / Banker's Rounding) in the bill service.
