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 num-

	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);
