# itermaxabs > Compute the maximum absolute value of all [iterated][mdn-iterator-protocol] values.
## 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 ```
## 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 ```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 console.log( 'maxabs: %d.', m ); ```
