Class X86.Fma
FMA intrinsics
Namespace: Unity.Burst.Intrinsics
Syntax
public static class Fma : objectProperties
| Name | Description |
|---|---|
| IsFmaSupported | Evaluates to true at compile time if FMA intrinsics are supported. Burst ties FMA support to AVX2 support to simplify feature sets to support. |
