Description
Compare label resolution on a common per-mass basis.
Food energy and label values depend on the declared nutrient factors, serving basis and rounding convention. A numerical fraction or rounding envelope does not select a regulatory rule, establish food quality or determine individual nutritional needs.
Compare label resolution on a common per-mass basis.
When to use this tool
Use Nutrient Label Resolution Gap when checking one explicit energy, label-resolution or rounding term.
How to use the tool and how it works
- Enter firstQuantum, secondQuantum, firstServingMass, secondServingMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read firstPerMassQuantum, secondPerMassQuantum, gap. Use the output convention below.
Compare label resolution on a common per-mass basis. Require positive quanta and serving masses; divide each quantum by its serving mass and return first-minus-second gap.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstQuantum | First Quantum | Required. Finite number; strictly above 0. |
| secondQuantum | Second Quantum | Required. Finite number; strictly above 0. |
| firstServingMass | First Serving Mass | Required. Finite number; strictly above 0. |
| secondServingMass | Second Serving Mass | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| firstPerMassQuantum | First Per Mass Quantum | Required. Finite number. |
| secondPerMassQuantum | Second Per Mass Quantum | Required. Finite number. |
| gap | Gap | Required. Finite number. |

}Limitations and assumptions
- The same nutrient and compatible mass units are required; this does not compare actual nutrient concentrations.
- 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 applicable labeling method and matched food-composition basis; assess dietary implications with appropriate professional context.
