Review request for hive, Ashutosh Chauhan, Gunther Hagleitner, and Thejas Nair.


Bugs: HIVE-5382
    https://issues.apache.org/jira/browse/HIVE-5382


Repository: hive


Description
-------

Allow casting of exponential notation whenever possible. 
Limitations:
1. The exponential part will be limited between MIN_VAL and MAX_VAL of the data types even
if the final result might be within the boundaries.
2. Allow loss-less transformation using BigDecimal and Double types.
