Description
Label a supplied qibla bearing with its north-reference convention.
Textual and archival references depend on the collection, edition, numbering system, date convention and source attribution. A supplied surah/ayah or manuscript partition number is a locator, not verification of canonical limits or content. Permission, beneficiary shares and direction labels require their stated documentary context.
Label a supplied qibla bearing with its north-reference convention.
When to use this tool
Use Qibla Bearing Convention Label when you already have bearingDegrees, northReference, source and need to label a supplied qibla bearing with its north-reference convention.
How to use the tool and how it works
- Enter bearingDegrees, northReference, source. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require bearingDegrees in [0,360), northReference true, magnetic or grid and source nonempty; label degrees clockwise from the selected north.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| bearingDegrees | Bearing Degrees | Required. Finite number; minimum 0; strictly below 360. |
| northReference | North Reference | Required. Text; one of "true", "magnetic", "grid"; maximum UTF-16 length 8192. |
| source | Source | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"bearingDegrees": 120,
"northReference": "true",
"source": "Map A"
},
"output": {
"label": "120° clockwise from true north [Map A]"
}
}Limitations and assumptions
- No bearing is calculated, magnetic correction chosen or location/religious correctness established.
- 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 relevant original edition, manuscript, deed or stated authority for an interpretive or rights question. Use a complete calendar, directional or distribution method when computation is required; local locators and supplied labels do not infer those rules.
