Same issue seen for ROUND(n) or ROUND(n, decimal).


select name, round(134.45,0) from voter where voter_id=10;
+------------+------------+
|    name    |   EXPR$1   |
+------------+------------+
| [B@5591a832 | 134.0      |

0: jdbc:drill:schema=dfs> select name, round(134.45) from voter where voter_id=10;
+------------+------------+
|    name    |   EXPR$1   |
+------------+------------+
| [B@6b7b36f6 | 134.0      |

In oracle and postgres, both return an int (134) for the above queries.

> The TRUNC(n1) function should return the integer part of n1 as an int.  In drill, however,
the value returned is a decimal.  For example,
> select trunc(15.79) from voter where voter_id=10;
> returns 15.0
> The other database platforms return an int value of 15.
