About Random Number Generator
Set a minimum and maximum value, choose how many numbers to generate, and pick a decimal precision from 0 to 6 places. Optional toggles let you require unique values (no repeats) or sort results in ascending order. Results update instantly with a summary showing sum, average, minimum, and maximum.
Common uses include picking lottery numbers, rolling dice, generating test data, sampling survey participants, and classroom probability experiments. Copy individual values, copy the whole batch, or export everything as a CSV file.
Every number comes from the browser's cryptographically secure random number generator with rejection sampling, so the output is unbiased and truly random. Everything runs locally - nothing is sent to a server or stored.
