Running tests in rtestint:
********************** Problem 56 ***************
Input:
cos(x)

x + 1
Result:

%e (%e + 1) %pi

This differed from the expected result:
- 1
%e %pi
Incidentally that looks like a display bug, which is shown by all
Lisps; should be displayed as a ratio %pi/%e. Guessing that flags in
the car of %e^-1 are interfering with NFORMAT or DISPLA itself.
Interesting. But there must be something else going on:
|(%i1) %pi/%e; Evaluation took 0.0000 seconds (0.0200 elapsed) using
4.102 KB. - 1 (%o1) %e %pi (%i2) :lisp $%o1 ((MTIMES SIMP) ((MEXPT SIMP)
$%E -1) $%PI) (%i2) %pi/%gamma; Evaluation took 0.0000 seconds (0.0000
elapsed) using 3.906 KB. %pi (%o2) ────── %gamma (%i3) :lisp $%o2
((MTIMES SIMP) ((MEXPT SIMP) $%GAMMA -1) $%PI) |
So |%pi/%e| and |%pi/%gamma| have the same flags. I guess that means
|nformat| or |displa| has some kind of special case for |%e^-1|.
