Frequently Asked Questions
Is the random number generator free to use?
Yes, our random number generator is completely free to use. No registration or payment required.
Can I generate multiple random numbers?
Yes, you can generate up to 1000 random numbers at once. You can also choose to generate unique numbers or allow duplicates.
What's the difference between integer and decimal generation?
Integer generation produces whole numbers (e.g., 1, 2, 3), while decimal generation produces numbers with decimal places (e.g., 1.234, 2.567).
What is cryptographically secure generation?
Cryptographically secure generation uses secure random number generators suitable for security-sensitive applications like encryption keys, passwords, and tokens.
Can I generate unique random numbers?
Yes, you can uncheck "Allow duplicates" to generate unique random numbers. Note that for integers, the count cannot exceed the range size.
