SDL_cos - Compute the cosine of x.

       This function is available since SDL 3.2.0.

       Domain: -INF<=x<=INF

       Range: -1<=y<=1

       This  function  operates  on  double-precision  floating  point values, use SDL_cosf for single-precision
       floats.

       This function may use a different approximation across different versions, platforms and  configurations.
       i.e,  it can return a different value given the same input on different machines or operating systems, or
       if SDL is updated.

x      floating point value, in radians.
