EXTShaderAtomicFloat2 (LWJGL 3.3.1 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.EXTShaderAtomicFloat2

```
public final class EXTShaderAtomicFloat2
extends java.lang.Object
```
This extension allows a shader to perform 16-bit floating-point atomic operations on buffer and workgroup memory as well as floating-point atomic minimum and maximum operations on buffer, workgroup, and image memory. It advertises the SPIR-V AtomicFloat16AddEXT capability which allows atomic add operations on 16-bit floating-point numbers and the SPIR-V AtomicFloat16MinMaxEXT, AtomicFloat32MinMaxEXT and AtomicFloat64MinMaxEXT capabilities which allow atomic minimum and maximum operations on floating-point numbers. The supported operations include OpAtomicFAddEXT, OpAtomicFMinEXT and OpAtomicFMaxEXT.
