Description
Calculate net issued food-lot quantity after subtracting returned quantity.
Food-assistance records track sources, quantities, vouchers, transfers and purchasing units. Nominal person-rations and whole-pack costs depend on supplied assumptions; they do not determine nutritional adequacy or legal entitlements. Returned quantities also do not establish that food can safely be redistributed.
Calculate net issued food-lot quantity after subtracting returned quantity.
When to use this tool
Use Food Bank Returned Lot Quantity when checking the stated supplied assistance inventory, quantity or cost convention.
How to use the tool and how it works
- Enter issuedQuantity, returnedQuantity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read netIssuedQuantity. Use the output convention below.
Require nonnegative issued and returned quantities. Return issued-returned as signed netIssuedQuantity.1
| Input field | Meaning and units | Accepted input |
|---|---|---|

}Limitations and assumptions
- Returns may exceed current issues; no actual stock, custody, acceptance for redistribution or food safety is established.
- 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 verified inventory and program records with qualified nutrition, food-safety and humanitarian professionals for actual dietary, distribution or benefit decisions.
