@stdlib/constants-float64-pinf

What is @stdlib/constants-float64-pinf?

@stdlib/constants-float64-pinf is a package that provides a constant representing positive infinity for double-precision floating-point numbers (float64). This can be useful in various mathematical computations and comparisons where positive infinity is a meaningful value.

What are @stdlib/constants-float64-pinf's main functionalities?

Accessing Positive Infinity

This feature allows you to access the positive infinity constant directly from the package. It can be used in mathematical operations where positive infinity is required.

const PINF = require('@stdlib/constants-float64-pinf');
console.log(PINF); // Output: Infinity

Comparisons with Positive Infinity

This feature demonstrates how to use the positive infinity constant in comparisons. It can be useful for checking if a value has overflowed to positive infinity.

const PINF = require('@stdlib/constants-float64-pinf');
const value = 1e308 * 2;
console.log(value === PINF); // Output: true

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!
