Description
Measure a room upgrade's signed rate difference.
Hospitality records distinguish seating count, booking category, reset time, package prices and stock flows. A tax fraction based on net differs from a tax share of gross, and a seat count does not prove a usable layout. Supplies, service preferences and dietary allocations need verified operational records.
Measure a room upgrade's signed rate difference.
When to use this tool
Use Hotel Room Upgrade Price Difference when you already have originalRate, upgradedRate and need to measure a room upgrade's signed rate difference.
How to use the tool and how it works
- Enter originalRate, upgradedRate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return upgradedRate-originalRate using a common currency and charging period.1
| Input field | Meaning and units | Accepted input |

"output": {
"signedGap": 5
}
}Limitations and assumptions
- Signed rates are retained; no booking terms, tax, availability or actual payable upgrade amount is determined.
- 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
Reconcile actual reservations, layouts, service preferences, invoices and inventories for operational questions. Apply the full menu, tax and dietary requirements when local counts, buffers or pricing terms cannot establish availability or suitability.
