NAMEfixtorad_r - Constant to convert angles in fixed point format to radians. Allegro game programming library.SYNOPSIS#include <allegro.h>extern const fixed fixtorad_r; DESCRIPTIONThis 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); SEE ALSOfixmul(3), radtofix_r(3)
