Description
Return leaf length under a petiole-inclusion policy.
Botanical measurements use explicit specimen geometry, pixel scales, length origins and angular direction. A projected-area ratio or geometric contribution summarizes supplied measurements without identifying a species, recovering an actual shape or establishing biological health.
Return leaf length under a petiole-inclusion policy.
When to use this tool
Use Leaf Petiole Inclusion Base Flag when checking the stated plant-measurement, geometry or angular convention.
How to use the tool and how it works
- Enter bladeLength, petioleLength, includePetiole. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read reportedLength, petioleFraction. Use the output convention below.
Return leaf length under a petiole-inclusion policy. Require nonnegative blade/petiole lengths with positive sum; reportedLength adds petiole only when includePetiole, petioleFraction always divides petiole by blade+petiole.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| bladeLength | Blade Length | Required. Finite number; minimum 0. |
| petioleLength | Petiole Length | Required. Finite number; minimum 0. |
| includePetiole | Include Petiole | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| reportedLength | Reported Length | Required. Finite number. |
| petioleFraction | Petiole divided by full blade-plus-petiole length, independently of reportedLength policy. | Required. Finite number. |

}Limitations and assumptions
- Reported and fraction denominators follow different explicit bases; no botanical measurement protocol or leaf morphology is 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
Inspect the specimen and measurement protocol, apply verified calibration and use an appropriate biological or geometric model for substantive interpretation.
