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.
