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);
