- Choose integer or decimal mode, enter minimum and maximum, and set quantity and decimal places.
How to use it
- 1.Choose integer or decimal mode, enter minimum and maximum, and set quantity and decimal places.
- 2.Enable unique values if needed, then Generate and copy the list.
Limits and notes
- Bounds are limited to ±10^9, quantity to 1000, and decimals to 0–6. Decimal bounds round inward; an interval with no value at that precision is rejected. Requires browser cryptographic randomness.
