Well, you got the log(x,y) from the documentation. So we should
put info on valuation there too. Thanks for the hints.
Please don't. They are quite unrelated. They just happen to agree on
perfect powers of the base.
sage: valuation(9,2)
0
sage: log(9,2)
log(9)/log(2)
sage: log(9,2).n()

Yes, but if the user knows in advance that the answer will be an integer
- as I did - then it makes sense to use valuation() instead of log(),
and a carefully worded note to that effect in the documentation could be
very helpful to future users.
