Description
A signed outline elongation index normalizes the difference between length and width by their sum.
A signed outline elongation index normalizes the difference between length and width by their sum.1
Its convention differs from the ordinary length-to-width ratio.
When to use Elongation Factor Fancy Shape Calculator
Use this tool to apply the stated elongation factor fancy shape calculator operation with an explicit input and unit basis.
How to use Elongation Factor Fancy Shape Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualMeasuredLength, actualMeasuredWidth and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualMeasuredLength | Measured length, on the basis specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
| actualMeasuredWidth | Measured width, on the basis specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
Require positive length and width in matching units. Divide length minus width by length plus width; retain the sign.
elongation index = (L − W)/(L + W) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Signed (length−width)/(length+width) elongation index. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Length-to-Width Ratio Calculator. Length-to-width ratio records a gemstone outline's measured proportions.
For a related operation, use Ideal Round Diameter from Carat Lookup. Carat mass and face-up diameter depend on material density and cut geometry.
