#include "SDL3/SDL.h"

float SDL_randf_r(Uint64 *state);

If you want reproducible output, be sure to initialize with

SDL_srand () first.

There are no guarantees as to the quality of the random sequence produced, and this should not be used for security (cryptography, passwords) or where money is on the line (loot-boxes, casinos). There are many random number libraries available with different characteristics and you should pick one of those to meet any serious needs.

state

a pointer to the current random number state, this may not be NULL.

Returns a random value in the range of [0.0, 1.0).

This function is thread-safe, as long as the state pointer isn't shared between threads.

This function is available since SDL 3.2.0.
