Description
Return a supplied fragment-orientation sign product.
Anthropological records depend on source-specific labels, observation periods, coding choices and participant context. A ratio, cyclic index or kinship-code offset describes supplied data rather than identifying a social relationship or cultural meaning. Replacing names with aliases does not establish anonymity.
Return a supplied fragment-orientation sign product.
When to use this tool
Use Artifact Refit Orientation Sign when checking the stated observation, coding, chronology or record convention.
How to use the tool and how it works
- Enter firstOrientation, secondOrientation, reversedJoin. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read relativeOrientation. Use the output convention below.
Return a supplied fragment-orientation sign product. Require each orientation -1 or +1; relativeOrientation = first*second, negated when reversedJoin.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstOrientation | First Orientation | Required. Safe integer. |
| secondOrientation | Second Orientation | Required. Safe integer. |
| reversedJoin | Reversed Join | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| relativeOrientation | Relative Orientation | Required. Safe integer. |

}Limitations and assumptions
- This is a local sign convention rather than a full 3D pose, verified refit or actual fragment identity.
- 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
Consult the original field records, community context and appropriate ethical/privacy practices for cultural interpretation or disclosure decisions.
