# ArmNeonFloat32x4

Arm neon float32x4.

Last updated: 2026-09-09

Package: compute.simd | Status: source-declared

Tags: compute, compute.simd, cpu, function, simd, source-example, yeho

Describe and exercise bounded SIMD-style workloads and their fallback boundaries.

```yh
external ArmNeonFloat32x4() returns simdCapability
```


## Use ArmNeonFloat32x4

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

Verification: type checked

```yh
using compute.simd

// Describe and exercise bounded SIMD-style workloads and their fallback boundaries.
simdCapability result = ArmNeonFloat32x4()
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_simd__armneonfloat32x4"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

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

```

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.simd--ArmNeonFloat32x4/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


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