Hi @sunjincheng121 . Thanks for the review.
I already finished some changed for code cleaning and remove the duplicate
test case base on your comment.
There are some similar implements in other Database,
like MySQL, https://dev.mysql.com/doc/refman/5.7/en/bit-functions.html
Oracle, https://docs.oracle.com/cd/E22583_01/DR/help/BitShift.html
In Apache Spark, also exists similar implements,
