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