Description
Return signedGap = (reportedValue-suppliedReportingLimit)*(higherIsAbove ? 1 : -1).
A threshold comparison needs compatible units, a direction and boundary rules. A caller-provided limit or reporting bound is an input to the calculation; it does not establish which scientific, analytical or legal rule applies.
Return signedGap = (reportedValue-suppliedReportingLimit)*(higherIsAbove ? 1 : -1).
When to use this tool
Use Sample Reporting Limit Gap when comparing a supplied value, bound or elapsed time with an explicit reference.
How to use the tool and how it works
- Enter reportedValue, suppliedReportingLimit, higherIsAbove. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap, aboveUnderDirection. Inspect aboveUnderDirection before interpreting the associated values.
Return signedGap = (reportedValue-suppliedReportingLimit)*(higherIsAbove ? 1 : -1). aboveUnderDirection uses strict greater-than when higherIsAbove is true and strict less-than otherwise. Use the same unit and basis for both numeric inputs.1
| Input field | Meaning and units | Accepted input |

| suppliedReportingLimit | Supplied Reporting Limit | Required. Finite number. |
| higherIsAbove | Higher Is Above | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |
| aboveUnderDirection | Above Under Direction | Required. Boolean. |

}Limitations and assumptions
- Equality yields zero and false in either direction. Direction is a supplied interpretation rule; censored results, detection capability and regulatory exceedance are not determined.
- 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
Consult the applicable method or authoritative policy to establish the reference, especially for censored measurements and compliance decisions.
