# itersumabs
> Compute the sum of absolute values for all [iterated][mdn-iterator-protocol] values.
The sum of absolute values is defined as
## Usage
```javascript
var itersumabs = require( '@stdlib/stats/iter/sumabs' );
```
#### itersumabs( iterator )
Computes the sum of absolute values for all [iterated][mdn-iterator-protocol] values.
```javascript
var array2iterator = require( '@stdlib/array/to-iterator' );
var arr = array2iterator( [ 1.0, 2.0, -3.5, 4.0 ] );
var s = itersumabs( arr );
// returns 10.5
```
## 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.
- For iterators which can generate many values or which may output large numbers, care should be taken to prevent overflow.
## Examples
```javascript
var runif = require( '@stdlib/random/iter/uniform' );
var itersumabs = require( '@stdlib/stats/iter/sumabs' );
// Create an iterator for generating uniformly distributed pseudorandom numbers:
var rand = runif( -10.0, 10.0, {
'seed': 1234,
'iter': 100
});
// Compute the sum of absolute values:
var s = itersumabs( rand );
// returns
console.log( 'sumabs: %d.', s );
```
