🌟 Constants Float32 Fourth Root Epsilon

npm npm GitHub issues

📜 Description

This repository provides the fourth root of the single-precision floating-point epsilon value, specifically for 32-bit IEEE 754 representations. Understanding floating-point arithmetic is vital in many computing applications, especially in fields such as graphics, scientific computations, and data analysis.

Epsilon, denoted as eps, is the smallest difference between two floating-point numbers. When performing calculations, knowing this value can help avoid errors that arise from precision limitations.

📁 Table of Contents

🚀 Installation

To use the constants in your JavaScript or Node.js projects, you can install the package via npm:

bash npm install constants-float32-fourth-root-eps

🔧 Usage

After installation, you can import the constant in your JavaScript code as follows:

```javascript const fourthRootEps = require('constants-float32-fourth-root-eps');

// Now you can use fourthRootEps in your calculations console.log(fourthRootEps); ```

The constant fourthRootEps holds the fourth root of the float32 epsilon. It provides a useful precision threshold for floating-point calculations.

📊 Examples

Example 1: Precision Check

Here's a simple function to demonstrate how you might use this constant to check the precision of floating-point operations:

```javascript const fourthRootEps = require('constants-float32-fourth-root-eps');

function isWithinPrecision(a, b) { return Math.abs(a - b) < fourthRootEps; }

// Test with numbers const a = 0.1 + 0.2; const b = 0.3;

console.log(isWithinPrecision(a, b)); // true ```

Example 2: Using in Mathematical Functions

You can also leverage this constant in more complex mathematical operations to ensure accuracy:

```javascript const fourthRootEps = require('constants-float32-fourth-root-eps');

function approximateSquareRoot(num) { let guess = num / 2.0; let nextGuess = (guess + num / guess) / 2.0;

while (Math.abs(guess - nextGuess) > fourthRootEps) {
    guess = nextGuess;
    nextGuess = (guess + num / guess) / 2.0;
}

return guess;

}

console.log(approximateSquareRoot(16)); // Output: 4 ```
