NAME
       fixtorad_r - Constant to convert angles in fixed point format to radians. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       extern const fixed fixtorad_r;

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:

	  fixed rad_angle, binary_angle;
	  /* Set the binary angle to 90 degrees. */
	  binary_angle = 64;
	  /* Now convert to radians (about 1.57). */
	  rad_angle = fixmul(binary_angle, fixtorad_r);
