    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

```bash
npm install @stdlib/math-iter-ops
```

</section>

<section class="usage">

## Usage

```javascript
var ns = require( '@stdlib/math-iter-ops' );
```

#### ns

Namespace containing math operator iterators.

```javascript
var iterators = ns;
// returns {...}
```

The namespace contains the following functions for creating iterator protocol-compliant iterators:

## Examples

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

```javascript
var array2iterator = require( '@stdlib/array-to-iterator' );
var ns = require( '@stdlib/math-iter-ops' );

// Demonstrate operations with two iterators:
var arr1 = [ 2.0, 3.0 ];
var arr2 = [ 1.0, 4.0 ];
var itAdd = ns.iterAdd( array2iterator( arr1 ), array2iterator( arr2 ) );
var itDiv = ns.iterDivide( array2iterator( arr1 ), array2iterator( arr2 ) );
var itMul = ns.iterMultiply( array2iterator( arr1 ), array2iterator( arr2 ) );
var itSub = ns.iterSubtract( array2iterator( arr1 ), array2iterator( arr2 ) );

// Addition: 2+1=3, 3+4=7
console.log( itAdd.next().value );
// => 3.0
console.log( itAdd.next().value );
// => 7.0

// Division: 2/1=2, 3/4=0.75
console.log( itDiv.next().value );
// => 2.0
console.log( itDiv.next().value );
// => 0.75

// Multiplication: 2*1=2, 3*4=12
console.log( itMul.next().value );
// => 2.0
console.log( itMul.next().value );
// => 12.0

// Subtraction: 2-1=1, 3-4=-1
console.log( itSub.next().value );
// => 1.0
console.log( itSub.next().value );
// => -1.0

// Demonstrate broadcasting:
var itAdd3 = ns.iterAdd( array2iterator( [ 1.0, 2.0 ] ), 3.0 );

console.log( itAdd3.next().value );
// => 4.0
console.log( itAdd3.next().value );
// => 5.0
