# Validity, Accuracy, and Precision Under construction 🚧 We plan to add information regarding validity of end points, particularly with respect to date ranges, and also expected accuracy. Generally, calculated astronomical values are presented to 8 decimal places, which may exceed the expected accuracy in some cases. Calculated coordinates (e.g. latitude, longitudes in eclipse paths) are normally given to 6 decimal places. It's been our experience that having precision match or exceed expected accuracy is often advantageous - not in a scientific context but in that of day-to-day software development, where comparability of results is usually most helpful and the ability to detect changes in outputs can often signify an unintended or unexpected change in inputs, assumptions, algorithms or behaviors, even if the digits that changed are not in themselves practically significant. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.radiantdrift.com/getting-started/validity-accuracy-and-precision.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
