@adityaPsl This is due to the values themselves being stored as floating-point numbers, wherein things like `sum` aggregations are going to not operate as you'd expect compared to whole numbers. I think this GH issue describes it better than I did: [https://github.com/elastic/elasticsearch/issues/30529](https://github.com/elastic/elasticsearch/issues/30529)

Thank you joelgriffith , it worked. I changed the mapping from float to double.

Thank you,
