---------------------------------------------------------
Hi Gunther,
Thanks for the review for addressing those issues.
It seems like e notation explicitly means 10^value.
I need to look more into how java language handles similar scenarios .
One question is why cant we directly use 'Double.valueOf(string)' for this
conversion as defined in
http://developer.classpath.org/doc/java/lang/Double-source.html Theoretically,
it should tally with the results that we obtain if we cast one number type to
another number type in Hive.
The bottom line is that the issues that Gunther addressed in RB need to be
clearly understood and addressed before we can merge in the change. This will
be fixed by 0.13.
Thanks
Hari
