Package Exports

@stdlib/assert-is-finite-array

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-finite-array) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isFiniteArray

Test if a value is an array-like object containing only finite numbers.

Installation

npm install @stdlib/assert-is-finite-array

Usage

var isFiniteArray = require( '@stdlib/assert-is-finite-array' );

isFiniteArray( value )

Tests if a value is an array-like object containing only finite numbers.

var Number = require( '@stdlib/number-ctor' );

var bool = isFiniteArray( [ -3.0, new Number(3.0) ] );
// returns true

bool = isFiniteArray( [ -3.0, 'abc' ] );
// returns false

bool = isFiniteArray( [ -3.0, 1.0/0.0 ] );
// returns false

isFiniteArray.primitives( value )

Tests if a value is an array-like object containing only primitive finite numbers.

var Number = require( '@stdlib/number-ctor' );

var bool = isFiniteArray.primitives( [ -1.0, 0.0, 4.5 ] );
// returns true

bool = isFiniteArray.primitives( [ -1.0, 1.0/0.0 ] );
// returns false

bool = isFiniteArray.primitives( [ -3.0, new Number(2.0) ] );
// returns false

isFiniteArray.objects( value )

Tests if a value is an array-like object containing only Number objects having finite values.

var Number = require( '@stdlib/number-ctor' );

var bool = isFiniteArray.objects( [ new Number(-1.0), new Number(2.0) ] );
// returns true

bool = isFiniteArray.objects( [ -1.0, 0.0, 1.0 ] );
// returns false

bool = isFiniteArray.objects( [ -3.0, new Number(1.0) ] );
// returns false

Examples

var Number = require( '@stdlib/number-ctor' );
var isFiniteArray = require( '@stdlib/assert-is-finite-array' );

var bool = isFiniteArray( [ -5.0, 0.0, 2.0, 5.0 ] );
// returns true

bool = isFiniteArray( [ -4.0, -3.14, 1.0, 3.14 ] );
// returns true

bool = isFiniteArray( [ -1.0, new Number( -6.0 ), 2.0 ] );
// returns true

bool = isFiniteArray( [ -1.0, 'abc', 3.0 ] );
// returns false

bool = isFiniteArray( [ -2.3, 1.0/0.0, 3.0 ] );
// returns false

bool = isFiniteArray( [] );
// returns false
