I just installed 5.25.1 and was surprised when some of my code didn?t work
anymore.? I narrowed it down to:
(%i1) numer:true;
(%o1) true
(%i2) maybe(signum(1) = signum(7));
(%o2) false
(%i3) map(signum, [1, -1, 7, -7]);
(%o3) [1,-1,1.0,-1.0]
In particular note that signum of integer 1 is integer 1, but signum? of
some other positive integers is 1.0 which isn?t = 1
This behavior is different than, say, release 5.22 of Maxima.
