Dealing with Exponent Values in Mssql 2005

create table temp (num float)

insert into temp values (6520008854656651321653)

select * from temp
Returned Result:
num
6.52000885465665E+21

Expected Result:
num
6520008854656651321653


when i insert such large value (6520008854656651321653)  in the column with the data type as float , it gets stored in the exponential format (6.52000885465665E+21).

Now, after a while if i want to get the exact value i have entered, what should i be doing??

Please suggest if there is a way i can store any large value in the table as i give. what is the data type i have to use. Also to be noted,this column is

hugely used for calculation purpose. So, i want it to be stored in a way so that it doesn't hamper the existing calculation logics.
