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);
