    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```

<section class="usage">

## Usage

```javascript
var dtypeAlignment = require( '@stdlib/ndarray-base-dtype-alignment' );
```

#### dtypeAlignment( \[dtype] )

Returns the alignment (in bytes) for an underlying [array data type][@stdlib/ndarray/dtypes].

```javascript
var out = dtypeAlignment( 'float64' );
// returns 8

out = dtypeAlignment( 'generic' );
// returns null
```

If provided an unknown or unsupported data type, the function returns `null`.

```javascript
var out = dtypeAlignment( 'foobar' );
// returns null
```

If not provided a [data type][@stdlib/ndarray/dtypes] value, the function returns an object mapping [data type][@stdlib/ndarray/dtypes] strings to alignments (in bytes).

```javascript
var obj = dtypeAlignment();
// returns {...}
```
