Description
Return that rounding-range width and the supplied lower/upper inclusion flags.
Forensic measurement calculations require a known calibration, geometric model and uncertainty convention. A converted length, ratio or residual describes the supplied measurements; it does not establish common origin, identity or evidentiary strength.
Return that rounding-range width and the supplied lower/upper inclusion flags.
When to use this tool
Use Measurement Rounding Range Width when you need an explicit image or physical-measurement term.
How to use the tool and how it works
- Enter quantum, lowerInclusive, upperInclusive. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read width, lowerIncluded, upperIncluded. Inspect lowerIncluded, upperIncluded before interpreting the associated values.
Require positive quantum. Return that rounding-range width and the supplied lower/upper inclusion flags.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| quantum | Quantum | Required. Finite number; strictly above 0. |
| lowerInclusive | Lower Inclusive | Required. Boolean. |
| upperInclusive | Upper Inclusive | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| width | Width or interval span on the measurement basis above. | Required. Finite number. |
| lowerIncluded | Lower Included | Required. Boolean. |
| upperIncluded | Upper Included | Required. Boolean. |

}Limitations and assumptions
- No measured center, rounding method, interval endpoints or measurement uncertainty is inferred; the flags remain caller policy.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the validated measurement method and original evidence for interpretation. Include calibration, geometry, uncertainty and the full evidentiary context rather than turning a numerical match into an identification.
