Description
Calculate supplied lost-input share and retained amount.
Agroecological metrics depend on sampling units, nonoverlapping coverage categories, mass bases and area denominators. Yield per whole plot differs from yield per allocated crop area, and literal crop-code richness per area is not rarefied diversity. Local count expansion assumes comparable density beyond the sampled segment.
Calculate supplied lost-input share and retained amount.
When to use this tool
Use Resource Loop Lost Input Share when you already have lostInputAmount, totalInputAmount and need to calculate supplied lost-input share and retained amount.
How to use the tool and how it works
- Enter lostInputAmount, totalInputAmount. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read fraction, remainder. Use the output convention below.
Require totalInputAmount>0 and lost in [0,total]; return lost/total and total-lost.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| lostInputAmount | Lost Input Amount | Required. Finite number; minimum 0. |
| totalInputAmount | Total Input Amount | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| fraction | Fraction | Required. Finite number. |
| remainder | Remainder | Required. Finite number. |

}Limitations and assumptions
- Quantity basis and accounting boundary must match. No input flow, ecological loss process, reuse efficiency or suitable practice is assessed.
- 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 complete survey, experiment and ecological analysis. Check detection, spatial variation, sampling representativeness and resource boundaries before interpreting local fractions or supplied labels as ecological benefits or suitable practices.
