Round off of decimals in SPS 8 and SPS 10

Hi,

We have created a computed column Column C = (Column A/Column B) with data type ‘DOUBLE’  in a calculation view in SPS 8 and we are getting more than 12 values after the decimal point as shown below.

        SPS 8 output    

                                                                                                                               Column C                                                                                            

When the same view is moved to SPS 10, for the same column, the decimal values got round off to 5 values as shown below.

     SPS 10 output

                                                                                                                            Column C

Kindly let us know

1. Why this is happening
2. Are there any configuration changes needs to be done to resolve this in SPS 10.
