> Create cbrt (cube root) UDF
> ---------------------------
>
> Key: HIVE-9858
> URL: https://issues.apache.org/jira/browse/HIVE-9858
> Project: Hive
> Issue Type: Improvement
> Components: UDF
> Reporter: Alexander Pivovarov
> Assignee: Alexander Pivovarov

>
> returns the cube root of a double value
> cbrt(double a) : double
> For example:
> {code}
> select cbrt(87860583272930481.0);
> OK
> 444561.0
> {code}
> I noticed that Math.pow(a, 1.0/3.0) and hive power UDF return
> 444560.99999999965 for the example above.
> However Math.cbrt returns 444561.0
> This is why we should have hive cbrt function in hive
