     35 ## Usage
     36 
     37 ```javascript
     38 var itercumax = require( '@stdlib/stats/iter/cumax' );
     39 ```
     40 
     41 #### itercumax( iterator )
     42 
     43 Returns an [iterator][mdn-iterator-protocol] which iteratively computes a cumulative maximum value.
     44 
     45 ```javascript
     46 var array2iterator = require( '@stdlib/array/to-iterator' );
     47 
     48 var arr = array2iterator( [ 2.0, 1.0, 3.0, -7.0, -5.0 ] );
     49 var it = itercumax( arr );
     50 
     51 var m = it.next().value;
     52 // returns 2.0
     53 
     54 m = it.next().value;
     55 // returns 2.0
     56 
     57 m = it.next().value;
     58 // returns 3.0
     59 
     60 m = it.next().value;
     61 // returns 3.0
     62 
     63 m = it.next().value;
     64 // returns 3.0
     65 ```

     75 ## Notes
     76 
     77 -   If an iterated value is non-numeric (including `NaN`), the function returns `NaN` for **all** future iterations. 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.
