Subject [jira] [Commented] (HIVE-22315) Support Decimal64 column division with decimal64 scalar
Date Fri, 11 Oct 2019 19:54:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-22315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949766#comment-16949766
] 

Gopal Vijayaraghavan commented on HIVE-22315:
---------------------------------------------

{code}
+  public long roundingDivision(long divident, long divisor, long valueHalf) {
+    return ((divident > 0) ^ (divisor > 0)) ?
+      (-Math.abs(divident) - Math.abs(valueHalf) + 1) / Math.abs(divisor) :
+      (Math.abs(divident) + Math.abs(valueHalf) - 1) / Math.abs(divisor);
+  }
{code}

needs some documentation, I know I'm going to forget this by next week.
