     29 The sequence of positive integers `1, 2, 3, 4, ...` (OEIS [A000027][oeis-a000027]) is also commonly referred to the sequence of **natural numbers**, **whole numbers**, and **counting numbers**; however, those terms are ambiguous due to the inclusion or exclusion of `0`.

     39 ## Usage
     40 
     41 ```javascript
     42 var iterPositiveIntegersSeq = require( '@stdlib/math/iter/sequences/positive-integers' );
     43 ```
     44 
     45 #### iterPositiveIntegersSeq( \[options] )
     46 
     47 Returns an iterator which generates a positive integer sequence.
     48 
     49 ```javascript
     50 var it = iterPositiveIntegersSeq();
     51 // returns <Object>
     52 
     53 var v = it.next().value;
     54 // returns 1
     55 
     56 v = it.next().value;
     57 // returns 2
     58 
     59 v = it.next().value;
     60 // returns 3
     61 
     62 // ...
     63 ```
     64 
     65 The returned iterator protocol-compliant object has the following properties:
     66 
     67 -   **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.
     68 -   **return**: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.
     69 
     70 The function supports the following `options`:
     71 
     72 -   **iter**: number of iterations. Default: `9007199254740991`.
     73 
     74 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.
     75 
     76 ```javascript
     77 var opts = {
     78     'iter': 2
     79 };
     80 var it = iterPositiveIntegersSeq( opts );
     81 // returns <Object>
     82 
     83 var v = it.next().value;
     84 // returns 1
     85 
     86 v = it.next().value;
     87 // returns 2
     88 
     89 var bool = it.next().done;
     90 // returns true
     91 ```

    101 ## Notes
    102 
    103 -   If an environment supports `Symbol.iterator`, the returned iterator is iterable.
