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);
