Frequently Asked Questions

Are the numbers truly random?

Yes! Our generator uses the browser's cryptographically secure pseudo-random number generator (CSPRNG) via window.crypto.getRandomValues(). This provides high-quality randomness suitable for most applications including gaming and giveaways.

Can I generate negative numbers?

Yes! Set a negative minimum value (e.g., -100) to generate numbers in negative ranges. The generator supports any integer range.

What's the maximum range for numbers?

Integers can range from -9,007,199,254,740,991 to 9,007,199,254,740,991 (safe integer range). Decimals have similar limits with decimal precision.

How many decimal places can I generate?

Decimal numbers are generated with up to 6 decimal places of precision. This provides a good balance between randomness and readability.

What's the difference between allowing and preventing duplicates?

Allow duplicates - each number is independent (like dice rolls). Prevent duplicates - each generated number is unique (like drawing raffle tickets without replacement).
