     37 ## Usage
     38 
     39 ```javascript
     40 var iterAcosh = require( '@stdlib/math/iter/special/acosh' );
     41 ```
     42 
     43 #### iterAcosh( iterator )
     44 
     45 Returns an [iterator][mdn-iterator-protocol] which iteratively computes the [hyperbolic arccosine][@stdlib/math/base/special/acosh].
     46 
     47 ```javascript
     48 var array2iterator = require( '@stdlib/array/to-iterator' );
     49 
     50 var it = iterAcosh( array2iterator( [ 1.0, 2.0 ] ) );
     51 // returns <Object>
     52 
     53 var r = it.next().value;
     54 // returns 0.0
     55 
     56 r = it.next().value;
     57 // returns ~1.317
     58 
     59 // ...
     60 ```
     61 
     62 The returned [iterator][mdn-iterator-protocol] protocol-compliant object has the following properties:
     63 
     64 -   **next**: function which returns an [iterator][mdn-iterator-protocol] 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.
     65 -   **return**: function which closes an [iterator][mdn-iterator-protocol] and returns a single (optional) argument in an [iterator][mdn-iterator-protocol] protocol-compliant object.

     74 
     75 ## Notes
     76 
     77 -   The domain of hyperbolic arccosine is restricted to `[1,+infinity)`. If an iterated value is outside of the domain, the returned [iterator][mdn-iterator-protocol] returns `NaN`.
     78 -   If an iterated value is non-numeric (including `NaN`), the returned [iterator][mdn-iterator-protocol] returns `NaN`. If non-numeric iterated values are possible, you are advised to provide an [`iterator`][mdn-iterator-protocol] which type checks and handles non-numeric values accordingly.
     79 -   If an environment supports `Symbol.iterator` **and** a provided [iterator][mdn-iterator-protocol] is iterable, the returned [iterator][mdn-iterator-protocol] is iterable.
