If <em>rounded</em> is on, and the argument is a real number, &lt;norm&gt; 
returns its absolute value. If <em>complex</em> is also on, &lt;norm&gt; 
returns the square root of the sum of squares of the real and imaginary 
parts of the argument. In all other cases, a result is returned in 
terms of the original operator.
