### Search before asking - [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar feature requirement. ### Description For services with a low rate of requests, for instance 1 per hour, the `cpm` aggregation function loses the requests when it is downsampled to hours or days treating it as effectively 0 requests. This lose of precision can misleading while being unable to different if there really has been a request or not. ### Use case Create a new function, for instance `cpm5d` (5 decimals), that doesn't lose precision after downsampling. We need at least 5 decimals if we want to represent as precise as possible 1 request in a concrete hour of a day, downsampled to days. The following example is 1 request in a concrete hour or a day. Which means at the end 1 request per day. 1 decimal: 1 / 1440 = 0 // We cannot different anymore 4 decimals: (1 * 10000) / 1440 = 6 5 decimals: (1 * 100000) / 1440 = 69 ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
