sdlAsin function

double sdlAsin(
  1. double x
)

Compute the arc sine of x.

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.

\param x floating point value. \returns arc sine of x, in radians.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.1.3.

      Double Function(Double x), double Function(double x)>('SDL_asin');
  return sdlAsinLookupFunction(x);
