sdlAcosf function stdinc

double sdlAcosf(
  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 single-precision floating point values, use SDL_acos for double-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 3.2.0.
