Gunther Hagleitner commented on HIVE-2693:
------------------------------------------
No, I don't feel strongly. I was playing with your patch this afternoon and am
starting to think this is better. For instance, one would run into the same
problem with BigInteger where at some point you'd run out of space in the
double and start having to use a big int literal. So it seems consistent to do
BigDecimal that way as well. Also, most cases are going to be covered with the
cast and when someone runs into issues there are ways to handle it.
