Description

When I export (either JSON or CSV) my int64 data using COMPASS, my resulting file has all the values rounded up when there are 18+ digits.  For example 8300000000000000321 becomes 8300000000000000000. 

Steps to Reproduce

Create a doc in a collection using int64 with a value of 8300000000000000321.  Then export that data either JSON or CSV using compass.

Expected Results

The data should not be changed (or rounded in any way).

Actual Results

Data is rounded (or modified).
