Description
Return signed adaptation-minus-source year gap and an earlier-adaptation flag.
Cultural source records can encode exact tokens, voices, time offsets and context budgets. Their literal structure can be summarized without determining authorship, cultural meaning, source authority or adequacy of interpretation.
Return signed adaptation-minus-source year gap and an earlier-adaptation flag.
When to use this tool
Use Edition Adaptation Timegap Sign when checking a supplied source-context or annotation convention.
How to use the tool and how it works
- Enter sourceYear, adaptationYear. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gapYears, precedesSource. Inspect precedesSource before interpreting the associated values.
Return signed adaptation-minus-source year gap and an earlier-adaptation flag. precedesSource uses adaptationYear < sourceYear.1
| Input field | Meaning and units | Accepted input |

| adaptationYear | Adaptation Year | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gapYears | Gap Years | Required. Safe integer. |
| precedesSource | Precedes Source | Required. Boolean. |

}Limitations and assumptions
- Years are supplied coordinates; relationships, source identity and historical dating are not authenticated.
- 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
