    VkBool32 shaderImageFloat32Atomics;
    VkBool32 shaderImageFloat32AtomicAdd;
    VkBool32 sparseImageFloat32Atomics;
    VkBool32 sparseImageFloat32AtomicAdd;
} VkPhysicalDeviceShaderAtomicFloatFeaturesEXT;

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• FEATURES SHADERBUFFERFLOAT32ATOMICS
  shaderBufferFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store, and exchange atomic operations on storage buffers.
• FEATURES SHADERBUFFERFLOAT32ATOMICADD
  shaderBufferFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic operations on storage buffers.
• FEATURES SHADERBUFFERFLOAT64ATOMICS
  shaderBufferFloat64Atomics indicates whether shaders can perform 64-bit floating-point load, store, and exchange atomic operations on storage buffers.
• FEATURES SHADERBUFFERFLOAT64ATOMICADD
  shaderBufferFloat64AtomicAdd indicates whether shaders can perform 64-bit floating-point add atomic operations on storage buffers.
• FEATURES SHADERSHAREDFLOAT32ATOMICS
  shaderSharedFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store, and exchange atomic operations on shared and payload memory.
• FEATURES SHADERSHAREDFLOAT32ATOMICADD
  shaderSharedFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic operations on shared and payload memory.
• FEATURES SHADERSHAREDFLOAT64ATOMICS
  shaderSharedFloat64Atomics indicates whether shaders can perform 64-bit floating-point load, store, and exchange atomic operations on shared and payload memory.
• FEATURES SHADERSHAREDFLOAT64ATOMICADD
  shaderSharedFloat64AtomicAdd indicates whether shaders can perform 64-bit floating-point add atomic operations on shared and payload memory.
• FEATURES SHADERIMAGEFLOAT32ATOMICS
  shaderImageFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store, and exchange atomic image operations.
• FEATURES SHADERIMAGEFLOAT32ATOMICADD
  shaderImageFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic image operations.
• FEATURES SPARSEIMAGEFLOAT32ATOMICS
  sparseImageFloat32Atomics indicates whether 32-bit floating-point load, store, and exchange atomic operations can be used on sparse images.
• FEATURES SPARSEIMAGEFLOAT32ATOMICADD
  sparseImageFloat32AtomicAdd indicates whether 32-bit floating-point add atomic operations can be used on sparse images.

If the VkPhysicalDeviceShaderAtomicFloatFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderAtomicFloatFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
