Comment:
Okay, so I've changed all six instances of "3.32192" (which seems to be
the most common approximation to log(10,2) in use). There are three
other references matching 3.32* (in rings/arith.py, interfaces/gp.py, and
libs/pari/gen.pyx) I left alone. Those all have at least 10 digits, so
the problem would be pushed to higher levels even if it occurs, and there
was in every case something I wasn't confident enough of to change. I
don't know much about how pari's precision works, for example.
I think it's a step in the right direction, anyhow.
