# SDL_SwapFloatBE Swap a floating point value from bigendian to native byte order. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_endian.h) ## Syntax ```c #define SDL_SwapFloatBE(x) SwapOnlyIfNecessary(x) ``` ## Macro Parameters | | | | ----- | ------------------------------------------- | | **x** | the value to swap, in bigendian byte order. | ## Return Value Returns `x` in native byte order. ## Remarks If this is running on a bigendian system, `x` is returned unchanged. This macro never references `x` more than once, avoiding side effects. ## Thread Safety It is safe to call this macro from any thread. ## Version This macro is available since SDL 3.2.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryEndian](CategoryEndian)
