Random Generation Formula Reference Chart
| Output Type | JavaScript Math Algorithm |
|---|---|
| Whole Integer | `Math.floor(Math.random() * (max - min + 1)) + min` |
| Decimal Number | `Math.random() * (max - min) + min` (rounded to 2 decimal places) |

Frequently Asked Questions (FAQs)
Q1: Is my data private on ConvertFreeTool?
Yes, 100% secure! All generations take place locally inside your browser using JavaScript. Your inputs and results are never uploaded or stored on external servers.
Q2: Are the generated numbers truly random?
The tool uses JavaScript's pseudo-random number generator (`Math.random()`), which is ideal for general applications, testing, and giveaways.
Q3: Can I generate negative numbers?
Yes! You can set minimum and maximum bounds to negative integers (e.g., from -50 to 50).
Q4: Is there any cost or subscription required?
No. This tool is completely free forever with no registration required and zero recurring subscriptions.
Q5: Do I need to install an app to use this generator?
No installations are necessary. The tool runs directly inside any modern web browser (Chrome, Firefox, Safari, Edge).
