The number 1,045,855,825 is certainly within the number of digits
of precision offered by the double datatype.  It is hard to determine
why Eric is seeing 1,046,000,000 rather than the desired result
without seeing all of the steps that were followed to calculate this

I recommend that Eric send an email to
and attach a dataset and do-file which can be used to reproduce
the result.
