PIN_AMOUNT field in Balance packet is rounded to nearest value

Hi,

I need some solution for the below scenario.

In first pipeline if i rate any cdr,the PIN_AMOUNT field in balance packet is coming correctly.But when this value is input for next pipeline then PIN_AMOUNT field in balance packet after rating it is rounded to nearest value.

Example ::

First pipeline after rating PIN_AMOUNT field is 10.857

605     0       1 /balance_group 177637432 0    826
607     0       10.857      1343654589      0                       0       0

Now this PIN_AMOUNT(10.857) is input for second pipeline  where i will do one to one rating.So after rating I am expecting 10.857 only but it is coming as 11

605     0       1 /balance_group 176657096 0    826
607     0       11      1343654589      0                       0       0

Please let me know how can i achieve this
