Description
Return expectedDryBasis=asReceived/dryFraction and supplied-minus-expected residual.
Nutrient labels can report elements, oxide equivalents or fractions on wet, dry or anhydrous material bases. Stoichiometric conversion requires a verified chemical identity and the correct factor direction. A supplied source label and numerical factor record assumptions rather than proving the underlying chemical definition.
Return expectedDryBasis=asReceived/dryFraction and supplied-minus-expected residual.
When to use this tool
Use Nutrient Moisture Basis Gap when checking the stated nutrient, moisture or elemental-equivalent convention.
How to use the tool and how it works
- Enter asReceived, dryFraction, suppliedDryBasis. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expectedDryBasis, residual. Use the output convention below.
Require nonnegative as-received and supplied dry-basis values with 0<dryFraction<=1. Return expectedDryBasis=asReceived/dryFraction and supplied-minus-expected residual.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| asReceived | As Received | Required. Finite number; minimum 0. |
| dryFraction | Dry mass/wet mass, strictly positive; as-received concentration divides by it. | Required. Finite number; maximum 1; strictly above 0. |
| suppliedDryBasis | Supplied Dry Basis | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expectedDryBasis | Expected Dry Basis | Required. Finite number. |
| residual | Signed supplied/calculated difference in the direction specified above. | Required. Finite number. |

}Limitations and assumptions
- Uses dry mass/wet mass as the denominator conversion; agreement does not verify analyte identity or assay quality.
- 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
Check the original label, analytical method and authoritative chemical definition before applying a conversion or comparing nutrient quantities.
