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, wellwritten, studied, documented, tested, measured, and highquality 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!
isInfinite
Test if a doubleprecision floatingpoint numeric value is infinite.
Installation
npm install @stdlib/mathbaseassertisinfinite
Usage
var isInfinite = require( '@stdlib/mathbaseassertisinfinite' );
isInfinite( x )
Tests if a doubleprecision floatingpoint numeric
value is infinite.
var bool = isInfinite( Infinity );
// returns true
bool = isInfinite( Infinity );
// returns true
Examples
var PINF = require( '@stdlib/constantsfloat64pinf' );
var NINF = require( '@stdlib/constantsfloat64ninf' );
var isInfinite = require( '@stdlib/mathbaseassertisinfinite' );
var bool = isInfinite( PINF );
// returns true
bool = isInfinite( NINF );
// returns true
bool = isInfinite( 5.0 );
// returns false
bool = isInfinite( 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.
