RH211-sys opened a new pull request, #4140: URL: https://github.com/apache/doris-website/pull/4140
## Versions - [x] dev - [ ] 4.x - [ ] 3.x - [ ] 2.1 or older (not covered by version/language sync gate) `gamma` is a new function on the master branch only, so there is no released version to document yet. ## Languages - [x] Chinese - [x] English ## Docs Checklist - [ ] Checked by AI - [x] Test Cases Built - [x] Updated required version and language counterparts, or explained why not - [x] If only one language changed, confirmed whether source/translation counterparts need sync Every example block on the page is the real output of the function, captured from a build of the dev branch, and both language versions are added in this PR, so no counterpart sync is outstanding. The function itself is covered by the regression test and the BE unit test in the Doris PR. ## Summary Document the `gamma` scalar function, which is being added to the Doris frontend and backend: - `docs/sql-manual/sql-functions/scalar-functions/numeric-functions/gamma.md` (English) - `i18n/zh-CN/docusaurus-plugin-content-docs/current/sql-manual/sql-functions/scalar-functions/numeric-functions/gamma.md` (Chinese) - the `numeric-functions/gamma` entry in `sidebars.ts` The page covers the definition (`gamma(n)` is `(n - 1)!` for a positive integer `n`, `gamma(0.5)` is `sqrt(pi)`), the special values the implementation produces (NULL at `0`, at every negative integer and at negative infinity; NaN for a NaN input; Infinity for positive infinity and above the double overflow threshold), and nine examples in both languages. Every example block is the real output of the function, taken from a build of the dev branch, so the values match what a reader gets, including the double-precision representation `24.000000000000004` for `gamma(5)`. -- This is an automated message from the Apache Git Service.
