Generate random numbers in any range. Choose integers or decimals, set count, allow or prevent duplicates. Free online random number tool.
A random number generator (RNG) produces a sequence of numbers that lack any predictable pattern, used in statistics, simulations, gaming, and cryptography.
Formula
X = floor(random() × (max − min + 1)) + minX = Generated random integer
min = Minimum value (inclusive)
max = Maximum value (inclusive)
random() = Uniformly distributed value in [0, 1)
Worked Example
Generate random integer between 1 and 6 (die roll)
Did you know? The RAND Corporation published 'A Million Random Digits with 100,000 Normal Deviates' in 1955, generated by an electronic roulette wheel — it was a bestseller among statisticians (source: RAND Corporation).
