# itermaxabs

> Compute the maximum absolute value of all [iterated][mdn-iterator-protocol] values.

<section class="usage">

## Usage

```javascript
var itermaxabs = require( '@stdlib/stats/iter/maxabs' );
```

#### itermaxabs( iterator )

Computes the maximum absolute value of all [iterated][mdn-iterator-protocol] values.

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

var arr = array2iterator( [ 1.0, -2.0, 3.0, -4.0 ] );

var m = itermaxabs( arr );
// returns 4.0
```

<section class="notes">

## Notes

-   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.

## Examples

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

```javascript
var runif = require( '@stdlib/random/iter/uniform' );
var itermaxabs = require( '@stdlib/stats/iter/maxabs' );

// Create an iterator for generating uniformly distributed pseudorandom numbers:
var rand = runif( -10.0, 10.0, {
    'seed': 1234,
    'iter': 100
});

// Compute the maximum absolute value:
var m = itermaxabs( rand );
// returns <number>

console.log( 'maxabs: %d.', m );
```
