## HLSL:
Determines if any components of the specified value are non-zero.
## Parameters
| Item | Description |
|--------------------------------------------------------|----------------------------------------|
| *x*
| \[in\] The specified value.
|
## Return Value
**True** if any components of the *x* parameter are non-zero; otherwise, **false**.
## Remarks
This function is similar to the [**all**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-all.md) HLSL intrinsic function. The **any** function determines if any components of the specified value are non-zero, while the **all** function determines if all components of the specified value are non-zero.

| *x* | [**scalar**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-intrinsic-functions.md), **vector**, or **matrix** | [**float**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/WinProg/windows-data-types.md), [**int**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/WinProg/windows-data-types.md), [**bool**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/WinProg/windows-data-types.md) | any |
| *ret* | [**scalar**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-intrinsic-functions.md) | [**bool**](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/WinProg/windows-data-types.md) | 1 |
## Minimum Shader Model
This function is supported in the following shader models.
| Shader Model | Supported |
|------------------------------------------------------------------------------------|-----------------------|
| [Shader Model 2 (DirectX HLSL)](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-sm2.md) and higher shader models | yes |
| [Shader Model 1 (DirectX HLSL)](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-sm1.md) | vs\_1\_1 and ps\_1\_4 |

Research direction
The issue names no source files or tests. Start by reading the linked original implementation issue (#70076) and the matrix requirement (#387), then identify the relevant HLSL `any` implementation and its existing coverage; done means matrix inputs follow the documented non-zero-component behavior.
