Now the output:
{code}
hive> select (cast (4.53 as decimal) / cast(25.86 as decimal)) * cast(0.087 as
decimal) from decimal_udf limit 1;
OK
0
hive> select (cast (4.53 as decimal(3,2)) / cast(25.86 as decimal(4,2))) *
cast(0.087 as decimal(3,3)) from decimal_udf limit 1;
OK

>
> When a decimal division is the first operation, the quotient cannot be
> multiplied in a subsequent calculation. Instead, a NULL is returned.
> The following yield NULL results:
> select (cast (4.53 as decimal) / cast(25.86 as decimal)) * cast(0.087 as
> decimal) from <tablename> limit 1;
> select cast (4.53 as decimal) / cast(25.86 as decimal) * cast(0.087 as
> decimal) from <tablename> limit 1;
> If we move the multiplication operation to be first, then it will
> successfully calculate the result.
