- Produce decimal samples in the 0.00-1.00 range at 3 decimal places.
- Run multiple scenarios and compare min/max/average summaries quickly.
Workflow Notes
- Unique mode is available for integers and validates range size before generation.
- Decimal mode supports configurable precision for simulation and sampling tasks.
- Use sorted output when you need predictable downstream parsing.
Common Use Cases
- Generate test IDs and sample values for QA scenarios.
- Create quick random picks for games and selection tasks.
- Produce bounded datasets for spreadsheet simulations.
