sqrt(2) has the CF [1;2,2,2,2,2,...] and yet it appears to be normal.  Similarly sqrt(5) has the CF [2;4,4,4,4,4,...]<p>It&#x27;s generally expected that non-integer square roots are normal, and yet they <i>always</i> have repeating CFs.<p>All that combines to mean that I would be surprised if <i>e</i> turns out not to be normal.
