Aman Sinha updated DRILL-2943:
------------------------------
Attachment: 0002-DRILL-2943-Parse-uppercase-E-for-scientific-notation.patch
Thanks for the review. Fixed the precedence bug and added expr parser specific
unit tests. Took out the order-by test but will suggest QA add some functional
tests.
