Description
Return display/loan object-days and time share.
Exhibition and catalog budgets distinguish object-days, area support, estimated missing text, date envelopes and monetary rates. Each total depends on its denominator and counting convention. A local estimate or premium term does not establish a historical date, an insurance entitlement or an actual exhibition condition.
Return display/loan object-days and time share.
When to use this tool
Use Exhibition Duration Object Day Term when reconciling the stated artwork coverage, duration, uncertainty envelope or cost term.
How to use the tool and how it works
- Enter objects, displayDays, loanDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read objectDisplayDays, objectLoanDays, displayFraction. Use the output convention below.
Return display/loan object-days and time share. Require nonnegative whole objects, loanDays > 0 and displayDays within [0,loanDays]; multiply each duration by object count, displayFraction = display/loan.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| objects | Objects | Required. Safe integer; minimum 0. |
| displayDays | Display Days | Required. Finite number; minimum 0. |
| loanDays | Loan Days | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| objectDisplayDays | Object Display Days | Required. Finite number. |
| objectLoanDays | Object Loan Days | Required. Finite number. |
| displayFraction | Display Fraction | Required. Finite number. |

}Limitations and assumptions
- This assumes identical durations per object; actual exhibition records, light exposure and contractual rights are not 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
Use verified exhibition, provenance and insurance records with the intended measurement and contractual conventions for substantive decisions.
