sdlCos function

double sdlCos(
  1. double x
)

Compute the cosine of x.

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.

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

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

\since This function is available since SDL 3.1.3.

Implementation

double sdlCos(double x) {
  final sdlCosLookupFunction = libSdl3.lookupFunction<Double Function(Double x),
      double Function(double x)>('SDL_cos');
  return sdlCosLookupFunction(x);
