A macro to determine if an SDL_PixelFormat is a floating point format.
Defined in <SDL3/SDL_pixels.h>
#define SDL_ISPIXELFORMAT_FLOAT(format)    \
      (!SDL_ISPIXELFORMAT_FOURCC(format) && \
       ((SDL_PIXELTYPE(format) == SDL_PIXELTYPE_ARRAYF16) || \
        (SDL_PIXELTYPE(format) == SDL_PIXELTYPE_ARRAYF32)))| format | an SDL_PixelFormat to check. | 
Returns true if the format is 10-bit, false otherwise.
Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.
It is safe to call this macro from any thread.
This macro is available since SDL 3.2.0.
