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);
