Are the numbers truly random?

The tool uses the browser's built-in Web Crypto API, which provides cryptographically secure randomness. The results are as close to true randomness as software can achieve.

Can I generate negative numbers?

Yes. Simply enter a negative value in the minimum field. For example, setting the range from -100 to 100 will produce numbers anywhere in that span.

Is there a limit to how many numbers I can generate at once?

There is no hard limit, but generating extremely large batches—millions of numbers—may slow down your browser. For most practical purposes the tool handles requests instantly.

Understanding Randomness

Computers generate random numbers using either pseudo-random number generators (PRNGs) or cryptographically secure random number generators (CSPRNGs). Toolin's tool leverages the Web Crypto API available in modern browsers, which provides cryptographically strong randomness. This means the output is suitable not only for casual use but also for scenarios where fairness and unpredictability are essential.
