The normalized vector is < x, y, z>/sqrt(x*x + y*y + z*z), so the result 
is < 1, 1, 1>/sqrt(3). This can't be perfectly represented in decimal or 
binary form, so you will get a lot of decimals from that #debug 
statement. You probably don't need to know this unless you are trying to 
simplify algebraic expressions.
