Compare numerical results with explicit tolerances and CPU-reference evidence.

```yh
external thing numericalComparisonResult
```

- bool passed: Stores passed as bool.
- text code: Stores code as text.
- text comparisonClass: Stores comparison class as text.
- int expectedCount: Stores expected count as int.
- int actualCount: Stores actual count as int.
- int mismatchCount: Stores mismatch count as int.
- float maximumDelta: Stores maximum delta as float.
- float expectedMean: Stores expected mean as float.
- float actualMean: Stores actual mean as float.
- float expectedVariance: Stores expected variance as float.
- float actualVariance: Stores actual variance as float.
- text failureEvidence: Stores failure evidence as text.
- numericalComparisonResult(bool passed, text code, text comparisonClass, int expectedCount, int actualCount, int mismatchCount, float maximumDelta, float expectedMean, float actualMean, float expectedVariance, float actualVariance, text failureEvidence): Numerical comparison result.
- Describe() returns text: Describe.

## Use numericalComparisonResult

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.parity

// Compare numerical results with explicit tolerances and CPU-reference evidence.
numericalComparisonResult sample = numericalComparisonResult(true, "code", "comparison Class", 1, 1, 1, 0.5, 1.0, 1.0, 1.0, 1.0, "failure Evidence")
Console.Log(Text.From(sample.passed))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_parity__numericalcomparisonresult"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "compute.parity"
version = "0.1.0"
path = "../../../yeho/packages/compute/parity"

[[dependencies]]
package = "compute.profiling"
version = "0.1.0"
path = "../../../yeho/packages/compute/profiling"

[[dependencies]]
package = "compute.simd"
version = "0.1.0"
path = "../../../yeho/packages/compute/simd"

[[dependencies]]
package = "compute.tensor"
version = "0.1.0"
path = "../../../yeho/packages/compute/tensor"

[[dependencies]]
package = "console"
version = "0.1.0"
path = "../../../yeho/packages/console"

[[dependencies]]
package = "diagnostics"
version = "0.1.0"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.parity--numericalComparisonResult/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## numericalComparisonResult.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using compute.parity

// Describe.
numericalComparisonResult instance = numericalComparisonResult(true, "code", "comparison Class", 1, 1, 1, 0.5, 1.0, 1.0, 1.0, 1.0, "failure Evidence")
text result = instance.Describe()
Console.Log(Text.From(result))

```

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
