Enter a minimum and maximum value, choose how many numbers you need, and the Random Number Generator produces a unique set of random numbers within your range. Control whether duplicates are allowed and how the results are sorted — great for lotteries, games, sampling, and more.

A pseudo-random number generator (PRNG) uses a mathematical algorithm or formula to produce numbers that appear random but are actually deterministic — given the same starting seed, you get the same sequence. A true random number generator uses a physical source of randomness, such as atmospheric noise or radioactive decay, to produce numbers that are genuinely unpredictable. For most everyday purposes like games, sampling, or picking lottery numbers, pseudo-random generators are perfectly adequate.
Yes. Set the <strong>Number Type</strong> field to <strong>Decimal</strong> and specify the number of decimal places you want. The generator will then produce random floating-point numbers within your chosen range rounded to that precision.
When duplicates are allowed, the same number can appear more than once in your results — each pick is independent. When duplicates are disabled, every generated number is unique within the set. If you request more unique numbers than the range contains (e.g., 15 unique numbers between 1 and 10), the generator will cap the output at the maximum possible unique count.
You can generate up to 500 numbers in a single run. For very large sets or statistical applications requiring thousands of numbers, you may need to run the generator multiple times or use a dedicated statistical software package.
Yes. You can set the minimum value to a negative number (as low as -1,000,000) and the maximum to any value above it. This lets you generate random numbers across ranges like -50 to 50 or -100 to 0.
Random number generators are used for lottery and raffle drawings, board and video games, statistical sampling, scientific simulations, cryptography, shuffling playlists, picking contest winners, assigning random groups or teams, and generating test data for software development.
Each time the generator runs, it uses a fresh random seed — typically derived from the current time in milliseconds — so the output is different every time. This ensures genuine unpredictability between runs.
Set <strong>Minimum Value</strong> to 1, <strong>Maximum Value</strong> to 10, and <strong>How Many Numbers</strong> to 1, then click Generate. The tool will display one random integer (or decimal, depending on your type setting) within that range.
