sdlAcos function

double sdlAcos(
  1. double x
)

Compute the arc cosine of x.

The definition of y = acos(x) is x = cos(y).

Domain: -1 <= x <= 1

Range: 0 <= y <= Pi

This function operates on double-precision floating point values, use SDL_acosf 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 cosine 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.

Implementation

double sdlAcos(double x) {
  final sdlAcosLookupFunction = libSdl3.lookupFunction<
      Double Function(Double x), double Function(double x)>('SDL_acos');
  return sdlAcosLookupFunction(x);
