iterFourthPowersSeq

$NPM version$ $Build Status$ $Coverage Status$

Create an iterator which generates a sequence of fourth powers.

Installation

npm install @stdlib/math-iter-sequences-fourth-powers

Usage

var iterFourthPowersSeq = require( '@stdlib/math-iter-sequences-fourth-powers' );

iterFourthPowersSeq( [options] )

Returns an iterator which generates a sequence of fourth powers.

var it = iterFourthPowersSeq();
// returns <Object>

var v = it.next().value;
// returns 0

v = it.next().value;
// returns 1

v = it.next().value;
// returns 16

v = it.next().value;
// returns 81

v = it.next().value;
// returns 256

// ...

The returned iterator protocol-compliant object has the following properties:

next: function which returns an iterator protocol-compliant object containing the next iterated value (if one exists) assigned to a value property and a done property having a boolean value indicating whether the iterator is finished.
return: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.

The function supports the following options:

iter: number of iterations. Default: 9741.

By default, the function returns a finite iterator to avoid exceeding the maximum safe double-precision floating-point integer. To adjust the number of iterations, set the iter option.

var opts = {
    'iter': 2
};
var it = iterFourthPowersSeq( opts );
// returns <Object>

var v = it.next().value;
// returns 0

v = it.next().value;
// returns 1

var bool = it.next().done;
// returns true

Notes

If an environment supports Symbol.iterator, the returned iterator is iterable.

Examples

var iterFourthPowersSeq = require( '@stdlib/math-iter-sequences-fourth-powers' );

// Create an iterator:
var opts = {
    'iter': 100
};
var it = iterFourthPowersSeq( opts );

// Perform manual iteration...
var v;
while ( true ) {
    v = it.next();
    if ( v.done ) {
        break;
    }
    console.log( v.value );
}
