Description
Return a symmetric decimal-rounding envelope for an estimate.
Research effect estimates depend on outcome definitions, unit conversions, orientation and statistical assumptions. A written rounding envelope describes reporting precision; an effect-size contribution or supplied interval is different from a fitted analysis, a confidence statement or evidence of clinical benefit.
Return a symmetric decimal-rounding envelope for an estimate.
When to use this tool
Use Chiropractic Review Effect Estimate Rounding Envelope when checking the stated effect-size, measurement or interval convention.
How to use the tool and how it works
- Enter estimate, decimalPlaces, nullValue. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read lower, upper, canIncludeNull. Inspect canIncludeNull before interpreting the associated values.
Return a symmetric decimal-rounding envelope for an estimate. Require decimalPlaces 0..15; lower/upper = estimate minus/plus 0.5*10^-places, canIncludeNull tests closed containment of nullValue.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| estimate | Estimate | Required. Finite number. |
| decimalPlaces | Decimal Places | Required. Safe integer; minimum 0; maximum 15. |
| nullValue | Null Value | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| lower | Estimate minus half one unit at the stated decimal precision; not a confidence bound. | Required. Finite number. |
| upper | Upper | Required. Finite number. |
| canIncludeNull | Can Include Null | Required. Boolean. |

}Limitations and assumptions
- This concerns written precision, not measurement or sampling uncertainty and not a significance test.
- 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
Use a complete, justified statistical analysis and original study data; distinguish reporting precision from sampling uncertainty and assess clinical relevance independently.
