Frequently Asked Questions
- Are these truly random numbers?
- They use a pseudorandom number generator (PRNG). This is suitable for games, sampling, and general purposes, but not for cryptographic or security applications.
- Can I get unique numbers only?
- Yes. Uncheck 'Allow Duplicates' and each generated number will be unique. The count is limited to the range size in this mode.
- What is the maximum count?
- You can generate up to 1,000 numbers at a time.
- Are decimal numbers supported?
- This generator produces whole integers only within the specified range (inclusive of both min and max).
