## README

# @plato/pmath

Plato math functions, based on [FDLIBM](https://www.netlib.org/fdlibm/readme).

This package is a [Node.js Addon](https://nodejs.org/api/addons.html) and is compiled from source during package install for the target platform and current version of Node.js.

_NOTE: Consider using [`node-pre-gyp`](https://www.npmjs.com/package/node-pre-gyp) to build/host prebuilt binaries instead._

## Usage

Install via Yarn:

```sh
yarn add @plato/pmath
```

Import the package and invoke exported math functions:

```ts
import { atan2, cos, sin } from "@plato/pmath";

const n = cos(10);

console.log(`cos(10) = ${n}`);
```

## Development

### Install & Update

When pulling updates or initially cloning this repo, make sure to update the submodules by running:

```sh
git submodule update --init
```

Afterwards, simply installing Yarn dependencies will build the native addon (the build scripts are triggered during package install). Run:

```sh
yarn
```

### Build

The build steps can be invoked manually as well:

To manually build FDLIBM, run:

```sh
yarn build-fdlibm
```

To manually build the native Node.js addon (requires FDLIBM to have been built previously), run:

```sh
yarn build
```

### Test

Execute unit tests (after the native addon is built) by running:

```sh
yarn test
```
