NAME
       al_fixhypot - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              al_fixed al_fixhypot(al_fixed x, al_fixed y)


DESCRIPTION
       Fixed point hypotenuse (returns the square root of x*x + y*y).  This
       should be better than calculating the formula yourself manually, since
       the error is much smaller.
