About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isNaN

> Test if a value is NaN.

Installation

npm install @stdlib/assert-is-nan

Usage

var isnan = require( '@stdlib/assert-is-nan' );

isnan( value )

Tests if a value is NaN.

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

var bool = isnan( NaN );
// returns true

bool = isnan( new Number( NaN ) );
// returns true

bool = isnan( 3.14 );
// returns false

bool = isnan( null );
// returns false

isnan.isPrimitive( value )

Tests if a value is a NaN primitive number.

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

var bool = isnan.isPrimitive( NaN );
// returns true

bool = isnan.isPrimitive( 3.14 );
// returns false

bool = isnan.isPrimitive( new Number( NaN ) );
// returns false

isnan.isObject( value )

Tests if a value is a Number object having a value of NaN.

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

var bool = isnan.isObject( NaN );
// returns false

bool = isnan.isObject( new Number( NaN ) );
// returns true

Examples

var Number = require( '@stdlib/number-ctor' );
var Symbol = require( '@stdlib/symbol-ctor' );
var isnan = require( '@stdlib/assert-is-nan' );

var bool = isnan( NaN );
// returns true

bool = isnan( new Number( NaN ) );
// returns true

bool = isnan( 5 );
// returns false

bool = isnan( '5' );
// returns false

bool = isnan( null );
// returns false

bool = isnan( Symbol( 'NaN' ) );
// returns false

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
