What is a Random Number Generator?
A Random Number Generator creates random integers or decimals within a specified range. Useful for games, testing, and selection.
How to use
Set minimum and maximum values, then generate random numbers. Options for quantity and uniqueness.
Frequently Asked Questions
What is a Random Number Generator?
A Random Number Generator (RNG) is a tool designed to produce a sequence of numbers that cannot be reasonably predicted better than by random chance. It is useful for simulations, games, picking lottery numbers, or making unbiased decisions.
How do I set the minimum and maximum range?
Enter the lowest possible number you want to generate in the 'Min' field and the highest possible number in the 'Max' field. The generator will produce a number between these two values, inclusive.
What is the difference between 'Allow Repeats' and 'Unique'?
If 'Allow Repeats' is on, the same number can appear multiple times in your list (e.g., rolling a die twice). If you select 'Unique' (or turn off repeats), the generator ensures that no number appears more than once in the current set.
Can I generate decimal numbers?
Yes, you can generate decimals by entering a decimal value in the Min or Max fields (e.g., 1.5 to 5.5) or by adjusting the precision setting to specify how many decimal places you need.
Why did I get an error when asking for unique numbers?
This error occurs when the range of numbers is smaller than the amount of unique numbers you requested. For example, you cannot ask for 5 unique numbers if your range is only 1 to 3.
Are these numbers cryptographically secure?
This tool uses a pseudo-random number generator (PRNG) which is sufficient for games, raffles, and statistics. It should not be used for cryptographic keys or high-security gambling unless specified otherwise.
