SDL_SwapFloat(3) SDL3 FUNCTIONS SDL_SwapFloat(3)

SDL_SwapFloat - Byte-swap a floating point number.

Defined in SDL3/SDL_endian.h

#include "SDL3/SDL.h"
SDL_FORCE_INLINE float SDL_SwapFloat(float x);

This will always byte-swap the value, whether it's currently in the native byteorder of the system or not. You should use

SDL_SwapFloatLE
or SDL_SwapFloatBE

instead, in most cases.

Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).

the value to byte-swap.

Returns x, with its bytes in the opposite endian order.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
