Let's dive into the details of what's being tested on MeasureThat.net.

**What is being tested?**

The benchmark is testing the performance of different libraries for handling large decimal numbers:

1. `bignumber.js`
2. `big.js`
3. `decimal.js`

Each library has its own implementation of arithmetic operations (addition, multiplication, etc.) and formatting functions (e.g., `toFixed()`).

**Options being compared**

The benchmark is comparing the performance of each library under two different scenarios:

1. **Native**: This option uses the built-in JavaScript support for decimal numbers, which is implemented in the ECMAScript standard.
2. **Native + toFixed**: This option adds an additional formatting step using the `toFixed()` function.

**Pros and Cons**

Here's a brief summary of each library's pros and cons:

* **bignumber.js**
	+ Pros: High-performance arithmetic operations, supports arbitrary-precision numbers, easy to use.
	+ Cons: Steeper learning curve due to its custom syntax and API.
* **big.js**
	+ Pros: Fast and efficient, supports decimal arithmetic with high precision, relatively simple API.
	+ Cons: Smaller community support compared to bignumber.js, some users find the API less intuitive.
* **decimal.js**
	+ Pros: Robust implementation of decimal arithmetic, easy to use, widely adopted in financial and scientific applications.
	+ Cons: Slower performance compared to bignumber.js and big.js, more complex API.

**Other considerations**

When choosing a library for handling large decimal numbers, consider the following factors:

* **Performance**: If high-performance arithmetic operations are crucial, bignumber.js or big.js might be a better choice. Otherwise, decimal.js' robust implementation and ease of use might be more suitable.
* **API simplicity**: If you prefer a simple and intuitive API, decimal.js or bignumber.js might be a better fit. Big.js has a relatively straightforward API but may require some learning curve for advanced users.
* **Community support**: If you need help with the library or want to contribute to its development, consider the size of each library's community.

**Library descriptions**

Here's a brief description of each library:

* **bignumber.js**: Developed by Mike McLaughlin, this library provides high-performance arithmetic operations for arbitrary-precision numbers. It's widely used in financial and scientific applications.
* **big.js**: Created by the Big.js project team, this library offers fast and efficient decimal arithmetic with high precision. It's designed for use cases where simple, intuitive API is sufficient.
* **decimal.js**: Developed by Mike McLaughlin (same author as bignumber.js), this library provides a robust implementation of decimal arithmetic with high precision. It's widely adopted in financial and scientific applications due to its ease of use and reliability.

**Special JS features or syntax**

None of the libraries mentioned above uses special JavaScript features or syntax that would require additional explanation.
