NAME

       SDL_acosf - Compute the arc cosine of x .

HEADER FILE

       Defined in SDL3/SDL_stdinc.h

SYNOPSIS

       #include "SDL3/SDL.h"

       float SDL_acosf(float x);

DESCRIPTION

       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.

FUNCTION PARAMETERS

       x      floating point value.

RETURN VALUE

       Returns arc cosine of x , in radians.

THREAD SAFETY

       It is safe to call this function from any thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
