Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

float SDL_asinf(float x);

The definition of y=asin(x) is x=sin(y) .

Domain: -1<=x<=1 Range: -Pi/2<=y<=Pi/2 This function operates on single-precision floating point values, use

SDL_asin
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.

x

floating point value.

Returns arc sine of x , in radians.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
