[SPARK-11408][SQL] display scientific notation correctly in DataFrame.show()
Initial implementation for displaying scientific notation in
DataFrame.show().
Advantages:
-- No type erasure issues, without using reflection utils.
Disadvantages:
-- Redundant code in case statements.
-- May degrade the performance (type castings, toStrings)
-- Looks hacky :(
Please suggest changes or a different approach altogether which doesn't
have above mentioned issues.
