Random Number Generator

Min (integer)

Max (integer)

Quantity

Uniqueness

Unique requires Qty ≤ range size.

Sort output

Optional seed

For UI reproducibility; numbers use random_int().

Fix the following:

Random Number Generator – Quick Cheat Sheet

Min/Max: Inclusive integer bounds. If you reverse them, the tool auto-swaps.
Quantity: How many numbers to generate (≥1).
Uniqueness: “All unique” means no repeats; you can’t request more unique numbers than the size of the range.
Sort: Sort ascending/descending or keep the original generated order.
Security: Values are drawn with PHP’s random_int() (CSPRNG). Sorting doesn’t change randomness—only the final order.
Copy: Results are provided as CSV and line-separated for quick pasting into spreadsheets, code, or lists.

Edge cases & notes

If “unique” is on and Quantity > (Max−Min+1), the tool will ask you to reduce Quantity or widen the range.
Very large ranges with “unique” use a memory-friendly method (set accumulation) to avoid huge arrays.
Optional seed is available for UI reproducibility expectations; actual draws use random_int() and ignore the seed.
