#include "SDL3/SDL.h"

float SDL_randf(void);

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.

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

All calls should be made from a single thread

This function is available since SDL 3.2.0.
