iterrange

Compute the range of all iterated values.

The range is defined as the difference between the maximum and minimum values.

Installation

npm install @stdlib/stats-iter-range

Usage

var iterrange = require( '@stdlib/stats-iter-range' );

iterrange( iterator )

Computes the range of all iterated values.

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

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

var v = iterrange( arr );
// returns 7.0

Notes

• If an iterated value is non-numeric (including NaN), the returned iterator returns NaN. If non-numeric iterated values are possible, you are advised to provide an iterator which type checks and handles non-numeric values accordingly.

Examples

var runif = require( '@stdlib/random-iter-uniform' );
var iterrange = require( '@stdlib/stats-iter-range' );

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

// Compute the range:
var v = iterrange( rand );
// returns <number>

console.log( 'Range: %d.', v );
