## Usage
```javascript
var iterIntegersSeq = require( '@stdlib/math/iter/sequences/integers' );
```
#### iterIntegersSeq( \[options] )
Returns an iterator which generates an interleaved integer sequence.
```javascript
var it = iterIntegersSeq();
// returns <Object>
var v = it.next().value;
// returns 0
v = it.next().value;
// returns 1
v = it.next().value;
// returns -1
v = it.next().value;
// returns 2
v = it.next().value;
// returns -2
// ...
```
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: `18014398509481984`.
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.
```javascript
var opts = {
'iter': 2
};
var it = iterIntegersSeq( opts );
// returns <Object>
var v = it.next().value;
// returns 0
v = it.next().value;
// returns 1
var bool = it.next().done;
// returns true
```

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

```javascript
var iterIntegersSeq = require( '@stdlib/math/iter/sequences/integers' );
// Create an iterator:
var opts = {
'iter': 100
};
var it = iterIntegersSeq( opts );
// Perform manual iteration...
var v;
while ( true ) {
v = it.next();
if ( v.done ) {
break;
}
console.log( v.value );
}
