🎲 Randomizers & Generators
Generate one or many random numbers inside any range.
Choose a range and quantity, then generate integers or decimals. Decimal mode supports 1–10 displayed decimal places, while integer mode can prevent duplicates when the range is large enough.
Generate one or more integers or fixed-precision decimal values inside a range for games, samples, classroom prompts, or everyday choices. Integer results can be sampled with or without replacement, while decimal mode supports 1–10 displayed places.
The selection runs in the browser and the entered list is not sent to Fieldlet. Agree on eligibility and reroll rules before using randomness with a group.
Last reviewed for accuracy:
Scenario: Choose three integers from 1 through 50 with duplicates disabled.
Result: The tool returns three different values, each inside the inclusive 1–50 range.
Candidate integers are selected with Web Crypto rejection sampling and accepted only if they have not already been drawn.
Fieldlet prefers cryptographically secure browser randomness. Rejection sampling discards raw values that would make some integers slightly more likely after a remainder operation, producing an even mapping across the requested range.
Allowing duplicates is equivalent to returning each number to the pool after it is drawn. Preventing duplicates removes each selected value for the rest of that draw. Choose the mode that matches the real-world process you are modeling.
These primary references document standards or definitions used in the explanation above.
Yes. Generate up to 100 values in one set and copy them together.
Yes for integer generation, as long as the selected range contains enough different integers for the requested quantity.
The generator uses Web Crypto when available and maps values with rejection sampling, avoiding the predictable and modulo-biased behavior that weaker approaches can introduce.
Choose a range and generate a value.
