Random Number Generator

Generate random numbers within a specified range.

Overview

The Random Number Generator produces random numbers within a user-defined range. It is useful for lotteries, games, decision-making, statistical sampling, and any situation that requires fair random selection.

Formula

Pseudo-random numbers are generated with a uniform distribution between the specified minimum and maximum values.

How to Use

  1. 1Enter the minimum and maximum values.
  2. 2Choose how many numbers to generate.
  3. 3Click 'Generate' to display the random numbers.
  4. 4Toggle the duplicate-allowed setting as needed.

Tips

  • For lottery picks, generate numbers in the appropriate range without duplicates.
  • Use it as a digital alternative to drawing lots for fair results.
  • For security-sensitive use cases (e.g., cryptographic keys), use a CSPRNG instead.
  • In statistical experiments, fix the seed value to reproduce results.

FAQ

Q. Are the generated numbers truly random?

Computer-generated numbers are pseudo-random — statistically uniform but not truly random. They are more than adequate for everyday draws and games.

Q. Can I generate numbers without duplicates?

Yes, enable the no-duplicates option to ensure every generated number is unique. Note that you cannot request more unique numbers than the range allows.

Q. Can decimal numbers be generated?

Yes, you can specify the number of decimal places to generate floating-point numbers instead of integers.
