Description
Form displayed±resolution/2 with positive resolution.
A similarity term depends on the comparison universe, missing-value policy, treatment of repeated features, and normalization. A score can also have a caller-selected value when its mathematical denominator vanishes. Those conventions matter before interpreting a threshold or comparing methods.
Form displayed±resolution/2 with positive resolution.
When to use this tool
Use Similarity Rounding Threshold Interval when you need this particular comparison term, normalization, domain condition, or empty-result policy in a larger matching workflow.
How to use the tool and how it works
- Enter displayed, resolution, threshold. 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, classification. Use the output convention below.
Form displayed±resolution/2 with positive resolution. Label certain-pass when lower>=threshold, certain-fail when upper<threshold, otherwise ambiguous.1

}Limitations and assumptions
- The envelope is not clamped to zero through one and assumes a supplied half-resolution model. Endpoint closure, actual rounding method, and statistical uncertainty are not established.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Compare methods only after aligning feature definitions, missingness, empty policies, multiplicities, and normalizers. Use a complete comparison when the tool returns only one contribution or count check.

Compare bounded score with bounded threshold using greater-than-or-equal when inclusive and strictly greater otherwise.
