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 3.1.3.
