# parityMismatch

A parity mismatch record carrying kind, index, expectedValue, actualValue, deltaValue, and related state.

Package: compute.parity | Status: source-declared

Tags: compute, compute.parity, cpu, method, parity, source-example, thing, yeho

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

```yh
external thing parityMismatch
```

- text kind: Stores kind as text.
- int index: Stores index as int.
- text expectedValue: Stores expected value as text.
- text actualValue: Stores actual value as text.
- text deltaValue: Stores delta value as text.
- text note: Stores note as text.
- Describe() returns text: Describe.

## Use parityMismatch

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.
parityMismatch sample = parityMismatch()
Console.Log(Text.From(sample.kind))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_parity__paritymismatch"
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"
path = "../../../yeho/packages/diagnostics"

```

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--parityMismatch/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## parityMismatch.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.
parityMismatch instance = parityMismatch()
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.
