al_fixtorad_r - Allegro 5 API
#include <allegro5/allegro.h>
const al_fixed al_fixtorad_r = (al_fixed)1608;
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);
