Description

This RFC proposes adding a C implementation, including a Node.js native addon, C benchmarks, and C examples, for the @stdlib/stats/base/dists/triangular/mode package.

When adding support, the following tasks should be completed:

1. A C source implementation should be added to a src folder within the package's directory.
2. A native add-on interface should be added in order to call the C implementation from JavaScript.
3. A JavaScript file should be added to the lib folder to allow benchmarking and unit testing the native implementation from JavaScript.
4. A new test file should be created which includes unit tests testing against expected behavior.
5. C benchmarks should be added which measure performance for the C source implementation.
6. A file containing C examples should be added to demonstrate example usage.
7. JavaScript benchmarks should be added which measure performance for the native add-on.
8. Build and configuration files should be added to allow compiling and running the C source implementation using project make commands (as documented below).
9. The README should be updated to include documentation for the added C API.

To provide a concrete example of what a PR adding the desired method should contain, see #3354, which is a PR adding a C implementation for the CDF of an arcsine distribution. This should provide an idea of what is expected.

Prerequisites

1. Review JavaScript implementation in lib/main.js and its required modules to identify all stdlib functions used.
2. Verify C implementations exist for each required function.

Other

Once the implementation is ready including C examples and benchmarks, we should be able to run the following make commands.

Build native add-on

NODE_ADDONS_PATTERN="@stdlib/stats/base/dists/triangular/mode" make install-node-addons

Run C examples

make examples-c-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/triangular/mode/examples/c/example.c"

Run C benchmarks

make benchmark-c-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/triangular/mode/benchmark/c/benchmark.c"

Run JavaScript benchmarks

make benchmark-javascript-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/triangular/mode/benchmark/benchmark.native.js"

Run all tests

make TESTS_FILTER=".*/@stdlib/stats/base/dists/triangular/mode/.*" test
