Description
Return rise/run and display the supplied rise:run pair.
Architectural quantities depend on dimension references, area boundaries, slopes, and construction allowances. A component calculation can describe a proposed geometry without establishing code compliance, structural adequacy, or buildability.
Return rise/run and display the supplied rise:run pair.
When to use this tool
Use Roof Pitch Rise Per Run Label when you need one explicit architectural geometry component using a common measurement basis.
How to use the tool and how it works
- Enter rise, run. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read risePerRun, label. Use the output convention below.
Require nonnegative rise and positive run. Return rise/run and display the supplied rise:run pair.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| rise | Rise | Required. Finite number; minimum 0. |
| run | Run | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| risePerRun | Rise Per Run | Required. Finite number. |
| label | Formatted label for the supplied components under the convention above. | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- Use matching length units; the ratio is not an angle or percent and no roof material, drainage, structural, or code requirement is checked.
- 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
Check the complete drawings, applicable requirements, and qualified design review before construction.
