sdlRandf function

double sdlRandf()

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

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).

\threadsafety All calls should be made from a single thread

\since This function is available since SDL 3.1.3.
