Nicolas Marniesse enhanced the akeneo/pim-api-docs repository by implementing configurable decimal places handling for API attribute definitions, addressing the need for precise control over numeric and metric attribute precision. He introduced new configuration options, including decimal_places_strategy and decimal_places, allowing API users to define and enforce decimal precision directly within the documentation. Using YAML and Swagger, Nicolas updated the API documentation to clarify enforcement by renaming the validation policy from "validate" to "forbid," ensuring stricter adherence to decimal rules. This focused contribution improved both data accuracy and developer guidance, reflecting a deep understanding of API documentation and configuration best practices.
