LLMs can make mistakes. Check important info.

The benchmark results suggest that the native `toString()` method in Firefox 103 is the fastest, with an average of 1584273664 executions per second.

Here's a rough ranking of the libraries and their performance:

1. Native `toString()`: 1584273664 executions per second
2. Big.js: 529927 executions per second
3. Decimal.js: 518418 executions per second
4. Bignumber.js: 477209 executions per second

The other libraries are not included in the results, but based on their name alone, it's likely that they are other decimal arithmetic libraries.

To provide a more precise answer, I would recommend checking out the individual benchmark results for each library to see which one is the fastest. Additionally, factors like system configuration, browser version, and hardware should be taken into account when comparing performance across different libraries.

However, based on the given data, it's clear that the native `toString()` method is significantly faster than the other libraries in this specific benchmarking scenario.
