SYNOPSIS

9              #include <allegro5/allegro.h>

DESCRIPTION

14       This  constant gives a ratio which can be used to convert a fixed point
15       number in binary angle format to a fixed point number in radians.
16
17       Example:
18
19                  al_fixed rad_angle, binary_angle;
20
21                  /* Set the binary angle to 90 degrees. */
22                  binary_angle = 64;
23
24                  /* Now convert to radians (about 1.57). */
25                  rad_angle = al_fixmul(binary_angle, al_fixtorad_r);
