I'll break down the provided benchmark and its options, explaining what's being tested, compared, and their pros/cons.

**Benchmark Overview**

The MeasureThat.net benchmark compares the performance of three JavaScript libraries:

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

All three libraries aim to provide decimal arithmetic with arbitrary-precision calculations. They are used for financial and scientific applications, among others.

**Library Descriptions:**

1.  **`bignumber.js`**: Created by Mike McLean, it's a widely-used JavaScript library for precise decimal arithmetic. It provides an implementation of the GNU Multiple Precision Arithmetic Library (GMP) in JavaScript.
2.  **`big.js`**: Also known as "BigDecimal.js", it's another popular JavaScript library for decimal arithmetic. It implements the IEEE 754 floating-point standard, which is used by most programming languages.
3.  **`Big`**: This library uses the `decimal.js` package and provides decimal arithmetic with a focus on precision and control.

**Test Cases:**

The benchmark consists of three test cases:

1.  **`bignumber 1`**: Tests the performance of multiplying a number by 10 to the power of 18 using `bignumber.js`.
2.  **`bignumber 2`**: Tests the performance of shifting a number by 18 positions using `bignumber.js`.
3.  **`big 1`**: Tests the performance of incrementing and converting a decimal value in `Big`.

**Comparison Options:**

The test cases compare the performance of each library for the specific operations mentioned above.

**Pros/Cons:**

*   **`bignumber.js`**
    *   Pros:
        *   Fastest execution time among all three libraries
        *   Optimized for performance and scalability
    *   Cons:
        *   May lack some advanced features compared to other libraries
*   **`big.js`**
    *   Pros:
        *   More feature-rich than `bignumber.js`
        *   Supports more operations and functions
    *   Cons:
        *   Slower execution time than `bignumber.js`
*   **`Big`**
    *   Pros:
        *   Provides more control over decimal arithmetic, especially for financial and scientific applications
        *   Fast execution times are comparable to `big.js`

**Special JS Features/Syntax:**

None mentioned explicitly in the provided benchmark information.
