[jira] [Created] (ARROW-11665) Document precision and scale parameters of decimal128()

ARF created ARROW-11665:
---------------------------

             Summary: Document precision and scale parameters of decimal128()
                 Key: ARROW-11665
                 URL: https://issues.apache.org/jira/browse/ARROW-11665
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Documentation, Python
            Reporter: ARF


In pyarrow, the `decimal128()` factory takes two parameters, `precision` and `scale`.

It is unclear to me, what these parameters are and how to use them. Unfortunately, the wikipedia entry for Decimal128 does not help either.
