@stdlib/constants-float64-max-base2-exponent

What is @stdlib/constants-float64-max-base2-exponent?

The @stdlib/constants-float64-max-base2-exponent package provides a constant representing the maximum base-2 exponent for a double-precision floating-point number (Float64). This is useful in various mathematical and scientific computations where understanding the limits of floating-point numbers is crucial.

What are @stdlib/constants-float64-max-base2-exponent's main functionalities?

Retrieve the maximum base-2 exponent for a Float64

This feature allows you to retrieve the maximum base-2 exponent for a double-precision floating-point number, which is 1023. This is useful for understanding the range and limitations of floating-point arithmetic in JavaScript.

const MAX_BASE2_EXPONENT = require('@stdlib/constants-float64-max-base2-exponent');
console.log(MAX_BASE2_EXPONENT); // 1023

Other packages similar to @stdlib/constants-float64-max-base2-exponent

mathjs

The mathjs package is a comprehensive math library for JavaScript and Node.js. It provides a wide range of mathematical constants, functions, and utilities. While it offers more extensive functionality compared to @stdlib/constants-float64-max-base2-exponent, it also includes the ability to work with floating-point numbers and their properties.

big.js

The big.js package is a small, fast JavaScript library for arbitrary-precision decimal arithmetic. It does not specifically provide the maximum base-2 exponent for Float64, but it allows for precise arithmetic operations that can handle very large and very small numbers, which can be an alternative approach to dealing with floating-point limitations.

decimal.js

The decimal.js package is another library for arbitrary-precision decimal arithmetic in JavaScript. Similar to big.js, it does not directly provide the maximum base-2 exponent for Float64, but it offers a way to perform high-precision calculations, which can be useful when working with the limitations of floating-point numbers.

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!
