=== Description
The `VK_KHR_shader_float16_int8` extension allows use of 16-bit
floating-point types and 8-bit integer types in shaders for arithmetic
It introduces two new optional features pname:shaderFloat16 and
pname:shaderInt8 which directly map to the code:Float16 and the code:Int8
SPIR-V capabilities.
The `VK_KHR_shader_float16_int8` extension also specifies precision
requirements for half-precision floating-point SPIR-V operations.
This extension does not enable use of 8-bit integer types or 16-bit
floating-point types in any <<interfaces-iointerfaces, shader input and
output interfaces>> and therefore does not supersede the
`<<VK_KHR_8bit_storage>>` or `<<VK_KHR_16bit_storage>>` extensions.
