    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>

<!-- Package usage documentation. -->

<section class="installation">

## Installation

```bash
npm install @stdlib/math-iter-sequences-negative-odd-integers
```

</section>

<section class="usage">

## Usage

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

```javascript
var iterNegativeOddIntegersSeq = require( '@stdlib/math-iter-sequences-negative-odd-integers' );
```

#### iterNegativeOddIntegersSeq( \[options] )

Returns an iterator which generates a sequence of negative odd integers.

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

```javascript
var it = iterNegativeOddIntegersSeq();
// returns <Object>

var v = it.next().value;
// returns -1

v = it.next().value;
// returns -3

v = it.next().value;
// returns -5

// ...
```

The returned iterator protocol-compliant object has the following properties:

-   **next**: function which returns an iterator protocol-compliant object containing the next iterated value (if one exists) assigned to a `value` property and a `done` property having a `boolean` value indicating whether the iterator is finished.
-   **return**: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.

The function supports the following `options`:

-   **iter**: number of iterations. Default: `4503599627370496`.

By default, the function returns a finite iterator to avoid exceeding the maximum safe double-precision floating-point integer. To adjust the number of iterations, set the `iter` option.

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

```javascript
var opts = {
    'iter': 2
};
var it = iterNegativeOddIntegersSeq( opts );
// returns <Object>

var v = it.next().value;
// returns -1

v = it.next().value;
// returns -3

var bool = it.next().done;
// returns true
```

## Notes

-   If an environment supports `Symbol.iterator`, the returned iterator is iterable.

## Examples

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

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

```javascript
var iterNegativeOddIntegersSeq = require( '@stdlib/math-iter-sequences-negative-odd-integers' );

// Create an iterator:
var opts = {
    'iter': 100
};
var it = iterNegativeOddIntegersSeq( opts );

// Perform manual iteration...
var v;
while ( true ) {
    v = it.next();
    if ( v.done ) {
        break;
    }
    console.log( v.value );
}
