Description
Return gap=secondExpiry-firstExpiry and earlierLot first, second, or tie under direct numeric comparison.
A logistics record separates ordered, reserved, dispatched, received, lost, and available quantities. It can also distinguish volume, mass, packaging, and cost bases. A balance or ratio checks supplied records and assumptions without verifying physical inventory, a contract, or safe loading.
Return gap=secondExpiry-firstExpiry and earlierLot first, second, or tie under direct numeric comparison.
When to use this tool
Use Lot Expiry Priority Gap when you need the particular supplied count, loading-budget, timing, or cost term in a logistics record.
How to use the tool and how it works
- Enter firstExpiry, secondExpiry. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gap, earlierLot. Use the output convention below.

}Limitations and assumptions
- Expiry values need one clock origin and unit. This is a supplied ordering term, not a product-safety, remaining shelf-life, stock-release, or expiration-policy decision.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Check the original stock, shipment, measurement, and contract records before acting on a balance. A full packing, routing, procurement, or load assessment may require more than the returned term.
