If you use numerical approximations in assume, then you are inserting
potentially false assertions into Maxima.
e.g.
assume(x>=%pi),numer
is (x >= %pi + 10^(-20)) might return true even if it is not
necessarily true mathematically.
If you want to have a database of assertions which are sometimes true,
but not always, maybe numerical
evaluation is OK. Maybe if the assertions already have floating point
numbers it might be OK.
However, %pi is not a floating point number.
