THE NUMBERS, EXPLAINED
How to use this calculator.
Supported partition is a single inclusive continuous numeric interval. The chosen step must fit within half the valid interval; generated cases cover just-outside, boundary and just-inside values.
Start with your inputs
Enter inclusive numeric field minimum, inclusive numeric field maximum, chosen boundary test step. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Inclusive numeric field minimum | 0 |
| Inclusive numeric field maximum | 10 |
| Chosen boundary test step | 1 |
A worked example
With the example inputs above, boundary candidate values is -1, 0, 1, 9, 10, 11. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Boundary candidate values | -1, 0, 1, 9, 10, 11 |
| Expected acceptance flags | Reject, Accept, Accept, Accept, Accept, Reject |
How this is calculated
Boundary candidate values
Place one test step outside and inside each inclusive endpoint.
Expected acceptance flags
Inclusive endpoints and interior points are valid; outside points are invalid.
Symbols and units
- a
- Inclusive numeric field minimum
- b
- Inclusive numeric field maximum
- c
- Chosen boundary test step
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Supported partition is a single inclusive continuous numeric interval. The chosen step must fit within half the valid interval; generated cases cover just-outside, boundary and just-inside values.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Boundary candidate values; Expected acceptance flags. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Supported partition is a single inclusive continuous numeric interval. The chosen step must fit within half the valid interval; generated cases cover just-outside, boundary and just-inside values.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
