fixtorad_r(3)                   Allegro manual                   fixtorad_r(3)

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);
