###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_randf Generate a uniform pseudo-random floating point number less than 1.0 ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c float SDL_randf(void); ``` ## Return Value (float) Returns a random value in the range of [0.0, 1.0). ## Remarks If you want reproducible output, be sure to initialize with [SDL_srand](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. ## Thread Safety All calls should be made from a single thread ## Version This function is available since SDL 3.1.3. ## See Also - [SDL_srand](SDL_srand) - [SDL_rand](SDL_rand) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryStdinc](CategoryStdinc)
