Benchmark: check Replace on number format

Tests:

test one
function printFloatFormato0( value, precisione) { // formato 1,234.56 / F° return Number.parseFloat(value).toFixed( precisione).toString(); } printFloatFormato0(10.55, 1);
test two
function printFloatFormato1( value, precisione) { // formato 1.234,56 / C° return Number.parseFloat(value).toFixed( precisione).toString().replace('.',','); } printFloatFormato1(10.55, 1);

Let's break down the provided benchmark and explain what's being tested.

**Benchmark Overview**

The benchmark is designed to measure the performance of JavaScript code that formats numbers in different ways. Specifically, it tests two variants:

1. `printFloatFormato0`: Formats numbers as "1,234.56 / F°"
2. `printFloatFormato1`: Formats numbers as "1.234,56 / C°"

**Comparison Options**

In this benchmark, the two options being compared are:

A) **No formatting**: Simply converts the number to a string using `Number.parseFloat` and `toFixed` without any additional processing.
B) **Formatting with comma separator**: Converts the number to a string using `Number.parseFloat`, `toFixed`, and a custom replacement for the decimal point (`.`) with a comma (`,`).

**Pros and Cons**

Option A (No formatting):

Pros:

* Simple and straightforward conversion
* Fast execution

Cons:

* May not be suitable for applications that require formatted numbers
* May lose precision due to rounding issues

Option B (Formatting with comma separator):

Pros:

* Provides a human-readable format for numbers
* May be more suitable for applications that require formatted numbers

Cons:

* Adds an extra step of processing, which can slow down execution
* Requires additional resources (e.g., locale settings) to handle the comma separator correctly

**Library and Special JS Features**

Neither of the test cases uses any external libraries. However, it does utilize some special JavaScript features:

* The `toFixed` method: This method formats a number to a specified precision.
* The `toString()` method: This method converts an object to a string.
* The `Number.parseFloat` function: This function parses a string as a floating-point number.

**Other Alternatives**

If you wanted to write similar benchmarks for other formatting options, you could consider testing:

* Formatting with decimal points (e.g., `1.234`)
* Formatting with thousands separators (e.g., `1,234`)
* Formatting with currency symbols (e.g., `$1234.56`)
* Using alternative formatting libraries or frameworks (e.g., Moment.js)

Keep in mind that these alternatives would require modifications to the benchmark script and setup.

I hope this explanation helps!
