SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              al_fixed al_fixatan(al_fixed x)

DESCRIPTION

14       This  function  finds the inverse tangent of a value using a lookup ta‐
15       ble.  The input value must be a fixed point radian.  The  inverse  tan‐
16       gent is the value whose tangent is x.

18       Example:
19
20                  al_fixed result;
21
22                  /* Sets result to binary angle 13. */
23                  result = al_fixatan(al_ftofix(0.326));
24

RETURN VALUE

26       Returns the inverse tangent of a fixed point value, measured as a fixed
27       point binary format angle.
