SDL_asin - Compute the arc sine of x .

       This function is available since SDL 3.2.0.

       The definition of y=asin(x) is x=sin(y) .

       Domain:  -1<=x<=1 Range: -Pi/2<=y<=Pi/2 This function operates on double-precision floating point values,
       use

       SDL_asinf
        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.
