    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>

<section class="usage">

## Usage

```javascript
var realmax = require( '@stdlib/utils-real-max' );
```

#### realmax( dtype )

Returns the maximum **finite** value capable of being represented by a numeric **real** type.

```javascript
var m = realmax( 'float64' );
// returns 1.7976931348623157e+308
```

The following numeric **real** types are supported:

-   `float64`: double-precision floating-point numbers
-   `float32`: single-precision floating-point numbers
-   `float16`: half-precision floating-point numbers
