Description
Return provided-minus-supplied ramp-landing length.
Architectural openings and clearances depend on measured boundaries, projection axes and a caller-supplied comparison criterion. A positive geometric margin is distinct from demonstrating code compliance, safe access or a complete door-swing envelope. Plan lengths and projected dimensions must not be mistaken for full spatial measurements.
Return provided-minus-supplied ramp-landing length.
When to use this tool
Use Ramp Landing Length Residual when checking the stated opening, projection or clearance geometry.
How to use the tool and how it works
- Enter providedLength, suppliedRequiredLength. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read residual. Use the output convention below.
Return provided-minus-supplied ramp-landing length. Require both lengths >= 0; residual = providedLength-suppliedRequiredLength.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| providedLength | Provided Length | Required. Finite number; minimum 0. |
| suppliedRequiredLength | Supplied Required Length | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| residual | Signed observed/calculated-minus-reference difference under the operation specified above. | Required. Finite number. |

}Limitations and assumptions
- A nonnegative residual only matches the supplied requirement; applicable regulations, geometry and safe access are not verified.
- 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 complete measured plans and a qualified architectural/engineering assessment with the applicable requirements for real construction or safety decisions.
