    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="installation">

## Installation

```bash
npm install @stdlib/ndarray-base-min-unsigned-integer-dtype
```

</section>

<section class="usage">

## Usage

<!-- eslint-disable id-length -->

```javascript
var minUnsignedIntegerDataType = require( '@stdlib/ndarray-base-min-unsigned-integer-dtype' );
```

#### minUnsignedIntegerDataType( value )

Returns the minimum ndarray [data type][@stdlib/ndarray/dtypes] for storing a provided unsigned integer value.

<!-- eslint-disable id-length -->

```javascript
var dt = minUnsignedIntegerDataType( 9999 );
// returns 'uint16'

dt = minUnsignedIntegerDataType( 3 );
// returns 'uint8'

dt = minUnsignedIntegerDataType( 1e100 );
// returns 'float64'
```

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

<section class="notes">

## Notes

-   Once a provided integer value exceeds the maximum values of all supported unsigned integer [data types][@stdlib/ndarray/dtypes], the function defaults to returning `'float64'`.

## Examples

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

<!-- eslint-disable id-length -->

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var exp2 = require( '@stdlib/math-base-special-exp2' );
var minUnsignedIntegerDataType = require( '@stdlib/ndarray-base-min-unsigned-integer-dtype' );

// Generate random powers:
var exp = discreteUniform( 100, 0, 40, {
    'dtype': 'generic'
});

// Determine the minimum data type for each generated value...
var v;
var i;
for ( i = 0; i < exp.length; i++ ) {
    v = exp2( exp[ i ] );
    console.log( 'min(%d) => %s', v, minUnsignedIntegerDataType( v ) );
}
