Random Numbers

What Random Numbers does

Set min, max, and count. Optional unique and sort. Count below 1 fails. Unique count cannot exceed the range size. Max 500 numbers.

Random Numbers sits in the Calculate group on purpose. It is not Number Sequence (Arithmetic sequence by start, end, step.) and not Dice Roll (Roll an N-sided die.). Choose this page when you need Integer list in a range. If you stretch Random Numbers into a neighbor’s job, the result will look wrong even though the site chrome looks the same.

How to use Random Numbers

1. Confirm you need Random Numbers, not Number Sequence (Arithmetic sequence by start, end, step.). Address: /calculate/random-numbers.
2. Enter the numbers or dates Random Numbers uses. Integer list in a range.
3. Read the result as Random Numbers defines it — not as Dice Roll (Roll an N-sided die.). Set min, max, and count. Optional unique and sort. Count below 1 fails. Unique count cannot exceed the range size. Max 500 numbers.
4. Random Numbers is an estimate in the browser, not professional advice. Integer range. Max 500. Unique limited by span.
5. Need a different formula? Try Dice Roll (Roll an N-sided die.) instead of stretching Random Numbers.

When not to use Random Numbers

Skip Random Numbers when a neighbor tool matches better — start with Number Sequence or Dice Roll — or when the description already warns the job will fail. In the tool’s own words: Set min, max, and count. Optional unique and sort. Count below 1 fails. Unique count cannot exceed the range size. Max 500 numbers.
