error with find_root when functions containing more than one built-in constant like %pi



Wait a sec... that doesn't work.  How *does* your proposal work so that

       (%e+1)^x,numer => (%e+1)^x

but

       (%e+1)^x,x=2, numer => 13.8

even if %e is represented as exp(1).

             -s

PS For symmetry, perhaps we should represent 1 as exp(0) :-) .
