SDL_fmod - Return the floating-point remainder of x/y

       This function is available since SDL 3.2.0.

       Divides x by y , and returns the remainder.

       Domain:  -INF<=x<=INF  ,  -INF<=y<=INF  , y!=0 Range: -y<=z<=y This function operates on double-precision
       floating point values, use

       SDL_fmodf
        for single-precision floats.

x      the numerator.

       y      the denominator. Must not be 0.
