@stdlib/math-base-assert-is-infinite

What is @stdlib/math-base-assert-is-infinite?

@stdlib/math-base-assert-is-infinite is a utility package that provides functions to check if a given value is infinite. This can be useful in various mathematical computations and validations where you need to ensure that values are within a finite range.

What are @stdlib/math-base-assert-is-infinite's main functionalities?

Check if a value is infinite

This feature allows you to check if a given value is either positive or negative infinity. It returns `true` if the value is infinite and `false` otherwise.

const isInfinite = require('@stdlib/math-base-assert-is-infinite');

console.log(isInfinite(Infinity)); // true
console.log(isInfinite(-Infinity)); // true
console.log(isInfinite(5)); // false
console.log(isInfinite(NaN)); // false

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!

isInfinite

Test if a double-precision floating-point numeric value is infinite.

Installation

npm install @stdlib/math-base-assert-is-infinite

Usage

var isInfinite = require( '@stdlib/math-base-assert-is-infinite' );

isInfinite( x )

Tests if a double-precision floating-point numeric value is infinite.

var bool = isInfinite( Infinity );
// returns true

bool = isInfinite( -Infinity );
// returns true

Examples

var PINF = require( '@stdlib/constants-float64-pinf' );
var NINF = require( '@stdlib/constants-float64-ninf' );
var isInfinite = require( '@stdlib/math-base-assert-is-infinite' );

var bool = isInfinite( PINF );
// returns true

bool = isInfinite( NINF );
// returns true

bool = isInfinite( 5.0 );
// returns false

bool = isInfinite( NaN );
// returns false
