Description
Subtract supplied tare from a livestock scale reading.
Animal records distinguish measurements, count-time exposure, mass fractions, percentages and nominal feed differences. Offered-minus-refused mass does not verify ingestion, and live-weight loss does not identify its cause. Source labels and scalar rates preserve supplied observations without assessing health or suitable care.
Subtract supplied tare from a livestock scale reading.
When to use this tool
Use Livestock Scale Tare Reading when you already have grossReading, tareReading and need to subtract supplied tare from a livestock scale reading.
How to use the tool and how it works
- Enter grossReading, tareReading. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read netReading. Use the output convention below.
Return grossReading-tareReading with signs preserved.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| grossReading | Gross Reading | Required. Finite number. |
| tareReading | Tare Reading | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| netReading | Net Reading | Required. Finite number. |

}Limitations and assumptions
- Use the same unit and conditions. Negative discrepancies are retained; no animal, scale calibration, actual mass or health status 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
Review original animal, feed, weighing and observation records with the complete professional assessment. Check sampling scope, calibration and welfare context before interpreting local fractions or count balances as management or clinical conclusions.
