    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>

> Generate a list of binary interface signatures from strided array [data types][@stdlib/strided/dtypes].

## Installation

```bash
npm install @stdlib/strided-base-binary-dtype-signatures
```

</section>

<section class="usage">

## Usage

```javascript
var signatures = require( '@stdlib/strided-base-binary-dtype-signatures' );
```

#### signatures( dtypes1, dtypes2, dtypes3\[, options] )

Generates a list of binary interface signatures from strided array [data types][@stdlib/strided/dtypes].

```javascript
var dtypes = [
    'float64',
    'float32',
    'int32',
    'uint8'
];

var sigs = signatures( dtypes, dtypes, dtypes );
// returns [ 'float32', 'float32', 'float32', ... ]
```

The function accepts the following arguments:

-   **dtypes1**: list of supported [data types][@stdlib/strided/dtypes] for the first input argument.
-   **dtypes2**: list of supported [data types][@stdlib/strided/dtypes] for the second input argument.
-   **dtypes3**: list of supported [data types][@stdlib/strided/dtypes] for the output value.
-   **options**: options.

The function accepts the following options:

-   **enums**: `boolean` flag indicating whether to return signatures as a list of [data type][@stdlib/strided/dtypes] enumeration constants. Default: `false`.

When the `enums` options is `false`, the function returns an array of [data type][@stdlib/strided/dtypes] strings. To return [data type][@stdlib/strided/dtypes] enumeration constants, set the `enums` option to `true`.

```javascript
var dtypes = [
    'float64',
    'float32',
    'int32',
    'uint8'
];
var options = {
    'enums': true
};

var sigs = signatures( dtypes, dtypes, dtypes, options );
// returns [...]
```

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   The function returns a strided array having a stride length of `3` (i.e., every `3` elements define a binary interface signature).
-   For each signature (i.e., set of three consecutive non-overlapping strided array elements), the first two elements are the input data types and the third element is the return data type.
-   All signatures follow type [promotion rules][@stdlib/ndarray/promotion-rules].

</section>

<!-- /.notes -->

<!-- Package usage examples. -->

<section class="examples">

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var dtypes = require( '@stdlib/strided-dtypes' );
var replace = require( '@stdlib/string-replace' );
var signatures = require( '@stdlib/strided-base-binary-dtype-signatures' );

// Get the list of supported strided array data types:
var dt = dtypes();

// Generate binary interface signatures:
var sigs = signatures( dt, dt, dt );

// Format the output:
var str = replace( JSON.stringify( sigs ), /("[^"]+","[^"]+","[^"]+"),/g, '$1,\n' );
console.log( str );
```
