## Install
### Node.js
```console
npm install @petamoriken/float16
```
### Deno
> [!NOTE]
> `Float16Array`, `DataView` methods for reading and setting float16 values, and `Math.f16round` are supported since Deno v1.43.
```console
deno add @petamoriken/float16
```
### Bun
```console
bun add @petamoriken/float16
```
## Import
### Node.js, Deno, Bun or Bundler
```js
import {
Float16Array, isFloat16Array, isTypedArray,
getFloat16, setFloat16,
f16round,
} from "@petamoriken/float16";
```
### Browser
Deliver a `browser/float16.mjs` or `browser/float16.js` file in the npm package
from your Web server with the JavaScript `Content-Type` HTTP header.
```html
<!-- Module Scripts -->
<script type="module">
import {
Float16Array, isFloat16Array, isTypedArray,
getFloat16, setFloat16,
f16round,
} from "DEST/TO/float16.mjs";
</script>
```
```html
<!-- Classic Scripts -->
<script src="DEST/TO/float16.js"></script>
<script>
const {
Float16Array, isFloat16Array, isTypedArray,
getFloat16, setFloat16,
f16round,
} = float16;
</script>
```
<details>
<summary>Or, you can use <a href="https://www.jsdelivr.com/package/npm/@petamoriken/float16">jsDelivr CDN</a>.</summary>
```html
<!-- Module Scripts -->
<script type="module">
import {
Float16Array, isFloat16Array, isTypedArray,

</script>
```
</details>
## Support engines
**This package only requires ES2015 features** and does not use
environment-dependent features (except for `inspect/`), so you can use it
without any problems. It works fine with
[the current officially supported versions of Node.js](https://github.com/nodejs/Release).
`Float16Array` implemented by `Proxy` and `Reflect`, so IE11 is never supported
even if you use polyfills.
### Pre-transpiled JavaScript files (CommonJS, IIFE)
`lib/` and `browser/` directories in the npm package have JavaScript files
already transpiled, and they have been tested automatically in the following
environments:
- Node.js: Active LTS
- Firefox: last 2 versions and ESR
- Chrome: last 2 versions
- Safari: last 2 versions
## API
### `Float16Array`
`Float16Array` is similar to `TypedArray` such as `Float32Array`
([MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array)).
```js
const array = new Float16Array([1.0, 1.1, 1.2, 1.3]);
for (const value of array) {
// 1, 1.099609375, 1.2001953125, 1.2998046875
console.log(value);
}
// Float16Array(4) [ 2, 2.19921875, 2.3984375, 2.599609375 ]
array.map((value) => value * 2);
```
### `isFloat16Array`
> [!WARNING]
> This API returns `false` for ECMAScript's native `Float16Array`
`isFloat16Array` is a utility function to check whether the value given as an
argument is an instance of `Float16Array` or not.
```js
const buffer = new ArrayBuffer(256);
// true
isFloat16Array(new Float16Array(buffer));
// false
isFloat16Array(new Float32Array(buffer));
isFloat16Array(new Uint16Array(buffer));
isFloat16Array(new DataView(buffer));
```
### `isTypedArray`
`isTypedArray` is a utility function to check whether the value given as an
argument is an instance of a type of `TypedArray` or not. Unlike
`util.types.isTypedArray` in Node.js, this returns `true` for `Float16Array`.
```js
const buffer = new ArrayBuffer(256);
// true
isTypedArray(new Float16Array(buffer));
isTypedArray(new Float32Array(buffer));
isTypedArray(new Uint16Array(buffer));
// false
isTypedArray(new DataView(buffer));
```
### `getFloat16`, `setFloat16`
`getFloat16` and `setFloat16` are similar to `DataView` methods such as
`DataView#getFloat32`
([MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DataView/getFloat32))
and `DataView#setFloat32`
([MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DataView/setFloat32)).
```ts
declare function getFloat16(view: DataView, byteOffset: number, littleEndian?: boolean): number;
declare function setFloat16(view: DataView, byteOffset: number, value: number, littleEndian?: boolean): void;
```
```js
const buffer = new ArrayBuffer(256);
const view = new DataView(buffer);
view.setUint16(0, 0x1234);
getFloat16(view, 0); // 0.0007572174072265625
// You can append methods to DataView instance
view.getFloat16 = (...args) => getFloat16(view, ...args);
view.setFloat16 = (...args) => setFloat16(view, ...args);
view.getFloat16(0); // 0.0007572174072265625
view.setFloat16(0, Math.PI, true);
view.getFloat16(0, true); // 3.140625
```
### `f16round` (alias: `hfround`)
`f16round` is similar to `Math.fround`
([MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/fround)).
This function returns nearest half-precision float representation of a number.
```ts
declare function f16round(x: number): number;
```
```js
Math.fround(1.337); // 1.3370000123977661
f16round(1.337); // 1.3369140625
```
## `Float16Array` limitations (edge cases)
<details>
<summary><code>Float16Array</code> has some limitations, because it is impossible to completely reproduce the behavior of <code>TypedArray</code>. Be careful when checking if it is a <code>TypedArray</code> or not by using <code>ArrayBuffer.isView</code>, and when using Web standards such as <code>structuredClone</code> and WebGL.</summary>
### Built-in functions
Built-in `TypedArray` objects use "internal slots" for built-in methods. Some
limitations exist because the `Proxy` object can't trap internal slots
([explanation](https://javascript.info/proxy#built-in-objects-internal-slots)).
This package isn't polyfill, in other words, it doesn't change native global
functions and static/prototype methods.
E.g. `ArrayBuffer.isView` is the butlt-in method that checks if it has the
`[[ViewedArrayBuffer]]` internal slot. It returns `false` for `Proxy` object
such as `Float16Array` instance.
```js
ArrayBuffer.isView(new Float32Array(10)); // true
ArrayBuffer.isView(new Float16Array(10)); // false
```
### The structured clone algorithm (Web Workers, IndexedDB, etc)
The structured clone algorithm copies complex JavaScript objects. It is used
internally when invoking `structuredClone()`, to transfer data between Web
Workers via `postMessage()`, storing objects with IndexedDB, or copying objects
for other APIs
([MDN](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm)).
It can't clone `Proxy` object such as `Float16Array` instance, you need to
convert it to `Uint16Array` or deal with `ArrayBuffer` directly.
```js
const array = new Float16Array([1.0, 1.1, 1.2]);
const cloned = structuredClone({ buffer: array.buffer });
```
### WebGL
WebGL requires `Uint16Array` for buffer or texture data whose types are
`gl.HALF_FLOAT` (WebGL 2) or `ext.HALF_FLOAT_OES` (WebGL 1 extension). Do not
apply the `Float16Array` object directly to `gl.bufferData` or `gl.texImage2D`
etc.
```js
// WebGL 2 example
const vertices = new Float16Array([
-0.5, -0.5, 0,
0.5, -0.5, 0,
0.5, 0.5, 0,
]);
const buffer = gl.createBuffer();
gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
// wrap in Uint16Array
gl.bufferData(gl.ARRAY_BUFFER, new Uint16Array(vertices.buffer), gl.STATIC_DRAW);
gl.vertexAttribPointer(location, 3, gl.HALF_FLOAT, false, 0, 0);
gl.bindBuffer(gl.ARRAY_BUFFER, null);
gl.enableVertexAttribArray(location);
```
### Others
See JSDoc comments in `src/Float16Array.mjs` for details. If you don't write
hacky code, you shouldn't have any problems.
</details>
## `Float16Array` custom inspection
<details>
<summary>Provides custom inspection for Node.js and Deno, which makes the results of <code>console.log</code> more readable.
</summary>
### Node.js
```js
import { Float16Array } from "@petamoriken/float16";
import { customInspect } from "@petamoriken/float16/inspect";
Float16Array.prototype[Symbol.for("nodejs.util.inspect.custom")] = customInspect;
```
### Deno
```ts
import { Float16Array } from "https://deno.land/x/float16/mod.ts";
import { customInspect } from "https://deno.land/x/float16/inspect.ts";
// deno-lint-ignore no-explicit-any
(Float16Array.prototype as any)[Symbol.for("Deno.customInspect")] = customInspect;
```
