+### Usage
+
+```c
+#include "stdlib/stats/base/dists/invgamma/quantile.h"
+```
+
+#### stdlib_base_dists_invgamma_quantile( p, alpha, beta )
+
+Evaluates the quantile function for an inverse gamma distribution.
+
+```c
+double y = stdlib_base_dists_invgamma_quantile( 0.8, 2.0, 1.0 );
+// returns ~1.213
+```
+
+The function accepts the following arguments:
+
+-   **p**: `[in] double` input value.
+-   **alpha**: `[in] double` shape parameter.
+-   **beta**: `[in] double` scale parameter.
+
+```c
+double stdlib_base_dists_invgamma_quantile( const double p, const double alpha, const double beta );

Subject: [PATCH 06/11] fix: add missing return annotation, fix JSDoc wording,
 improve test coverage, and remove redundant include

- Add missing `// returns NaN` on non-positive shape parameter example in native.js and main.js
- Fix 'rate parameter' to 'scale parameter' in main.js JSDoc
- Remove redundant `<stdbool.h>` include from src/main.c
- Fix test.native.js import ordering (tryRequire after tape, add PINF)
- Rename tape descriptions from 'negative' to 'nonpositive' for alpha/beta
- Add alpha=0 and beta=0 edge-case tests
- Add full PINF/NINF/NaN combination sub-assertions matching test.quantile.js

Subject: [PATCH 07/11] fix: revert index.js to standard pattern and align C
 files with conventions

- Revert lib/index.js to use direct main export without tryRequire
  (matching all 458 other distribution packages)
- Replace rand_double()/raw rand() with random_uniform(min,max) helper
  in benchmark.c and example.c
- Use pre-generated arrays with i%100 indexing in benchmark.c
- Use convention-matching print_results(elapsed) signature
- Update NAME define to 'invgamma-quantile'
- Use 25 iterations and Unicode symbols in example.c
- Remove return 0 from main() in benchmark.c and example.c
- Sync README C example with example.c
