al_fixtorad_r(3)                                              al_fixtorad_r(3)

NAME
       al_fixtorad_r - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              const al_fixed al_fixtorad_r = (al_fixed)1608;


DESCRIPTION
       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);


SEE ALSO
       al_fixmul(3), al_radtofix_r(3).
