how can we set single decimal point in stacked bar chart- total lable?

[kdr_Qv]

My segment lable's  are set to single decimal point  and it's showing properly as per my measure conditions..

but when  i see the total lables's it coming with 2 decimal points. how can we restrict this total  lable's into single decimal point?

  as  shown in  below  pic  total showing as 12.28  B But my expected result should be  12.2 B or 12.3 B either anything fine.

could you please help me any one on this...
