NAME

SDL_randf_r - Generate a uniform pseudo-random floating point number less than 1.0

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"

float SDL_randf_r(Uint64 *state);

DESCRIPTION

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.

FUNCTION PARAMETERS

state

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

RETURN VALUE

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

THREAD SAFETY

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

AVAILABILITY

This function is available since SDL 3.2.0.
