NAME

       SDL_asin - Compute the arc sine of x.

SYNOPSIS

       #include <SDL3/SDL_stdinc.h>

       double SDL_asin(double x);

DESCRIPTION

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

       Domain: -1 <= x <= 1

       Range: -Pi/2 <= y <= Pi/2

       This  function  operates  on  double-precision  floating point values, use SDL_asinf 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.

FUNCTION PARAMETERS

       x      floating point value.

RETURN VALUE

       Returns arc sine 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.
