Math-All

Examples

Here are some examples of using the MathAll.round function:

// Rounding to the nearest integer
const result1 = MathAll.round(14321.12345, 0); // Output: 14321

// Rounding to the nearest ten
const result2 = MathAll.round(14321.12345, 1); // Output: 14320

// Rounding to the second decimal place
const result3 = MathAll.round(14321.12344, -2); // Output: 14321.12

Overview

The math-all library provides an extended rounding solution in JavaScript, inspired by the familiar Math.round function. The library allows for precise rounding not only of decimal places but also for various significant digits, enhancing the flexibility of numeric rounding operations.

Installation

To install the math-all library, you can use the following npm command:

npm install math-all

Usage

Here is a basic example of using the MathAll.round function:

import { MathAll } from "math-all";

or

const { MathAll } = require("math-all");

// Example usage
const roundedValue = MathAll.round(14321.12345, -5);
console.log(roundedValue); // Output: 14321.12345

Features

1. Multi-Precision Rounding

The math-all library allows rounding not only for decimal places but also for various significant digits, providing a versatile solution for precise numeric rounding.

2. Familiar Interface

Designed with a similar interface to the built-in Math.round function, users can seamlessly integrate the MathAll.round function into their JavaScript applications.

3. Enhanced Precision Handling

The library includes enhanced precision handling to address potential issues associated with precision when using standard rounding formulas.

How It Works

The core rounding formula used by the math-all library is:

Math.round(copiedTarget / 10 ** digit) * 10 ** digit;

This formula ensures accurate rounding based on the specified digit.
