Details:

The following, from Octave 3.6.2-5 on Debian Sid, is incorrect:


> factor(10000000000000001)
ans = 2         3         5        11        17        73       101       137 
   69857   5882353


Obviously, 2 should not be a prime factor.

Also, this seems strange to me, using the same number:


> uint64(10000000000000001)
ans = 10000000000000000


For some reason, the last 1 turnes into a 0. Isn't this number well within the
range of uint64?
