# Usage

## Float16

```js
import { getFloat16, setFloat16 } from '@hqtsm/dataview';

const data = new Uint8Array(4);
const view = new DataView(data.buffer);
setFloat16(view, 0, Math.PI);
setFloat16(view, 2, Math.LN10, true);
console.assert(data.join(', ') === '66, 72, 155, 64');
console.assert(getFloat16(view, 0) === 3.140625);
console.assert(getFloat16(view, 2, true) === 2.302734375);
```

## Int24

```js
import { getInt24, setInt24 } from '@hqtsm/dataview';

const data = new Uint8Array(6);
const view = new DataView(data.buffer);
setInt24(view, 0, -1234);
setInt24(view, 3, -4567, true);
console.assert(data.join(', ') === '255, 251, 46, 41, 238, 255');
console.assert(getInt24(view, 0) === -1234);
console.assert(getInt24(view, 3, true) === -4567);
```

## Uint24

```js
import { getUint24, setUint24 } from '@hqtsm/dataview';

const data = new Uint8Array(6);
const view = new DataView(data.buffer);
setUint24(view, 0, 12345678);
setUint24(view, 3, 11223344, true);
console.assert(data.join(', ') === '188, 97, 78, 48, 65, 171');
console.assert(getUint24(view, 0) === 12345678);
console.assert(getUint24(view, 3, true) === 11223344);
```
