Dynamics Ax 2012 High Precision Value Support for Float

Hi  Everyone,

                        I am facing the new problem. That is I cant able to give a float value(7 digit Precision) into the Real or EDT's. It is only taking the 2 digit precision and it also round up the value in the 2nd digit. For Example if I give 48759.1234567, it is only taking the 2 precision ( 48759.12 ) and it is rounding up the value.  In this I want to display the total exact value like 48759.1234567 this. I have tried more EDT's and Real value for the table Fields. But I can't.    Is there any other way to take the full Precision of float value and store it exactly in a table column.....?

Please help me If you know about this..

You will be appreciated...

Thanks In Advance..
