NAME

       SDL_atanf - Compute the arc tangent of x.

SYNOPSIS

       #include <SDL3/SDL_stdinc.h>

       float SDL_atanf(float x);

DESCRIPTION

       The definition of y = atan(x) is x = tan(y).

       Domain: -INF <= x <= INF

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

       This  function  operates  on  single-precision  floating  point values, use SDL_atan for dboule-precision
       floats.

       To calculate the arc tangent of y / x, use SDL_atan2f.

       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 tangent of of x in radians, or 0 if x = 0.

THREAD SAFETY

       It is safe to call this function from any thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
