#include <allegro5/allegro.h> const al_fixed al_fixtorad_r = (al_fixed)1608;
Overview
This constant gives a ratio which can be used to convert a fixed point number in binary angle format to a fixed point number in radians.
Example:
-
al_fixed rad_angle, binary_angle; /* Set the binary angle to 90 degrees. */ binary_angle = 64; /* Now convert to radians (about 1.57). */ rad_angle = al_fixmul(binary_angle, al_fixtorad_r);
