Description
Return wornMinutes, subtracting missing only when excludeMissing.
Personal health and activity records use supplied observations, labels, and time intervals. A formatter or simple summary can organize those records without assessing health, diagnosing a condition, or recommending treatment.
Return wornMinutes, subtracting missing only when excludeMissing.
When to use this tool
Use Wearable Worn Missing Minute Denominator when you need a bounded personal-record calculation with explicit units and date conventions.
How to use the tool and how it works
- Enter scheduledMinutes, wornMinutes, missingMinutes, excludeMissing. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator. Use the output convention below.
Require wornMinutes within nonnegative scheduledMinutes and missingMinutes within wornMinutes. Return wornMinutes, subtracting missing only when excludeMissing.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| scheduledMinutes | Scheduled Minutes | Required. Safe integer; minimum 0. |
| wornMinutes | Worn Minutes | Required. Safe integer; minimum 0. |
| missingMinutes | Missing Minutes | Required. Safe integer; minimum 0. |
| excludeMissing | Exclude Missing | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Selected population, count, or duration base; inspect its documented zero handling. | Required. Safe integer. |

}Limitations and assumptions
- Nonwear is excluded in either branch and denominator may be zero; the tool does not infer wearing status, device accuracy, or a clinical activity measure.
- 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
Review the original observations and consult an appropriate health professional for clinical interpretation or care decisions.
