     It's also present in the HP-28C and HP-28S.  I can type equations
like:

     3=1.2^X

and I can have the calculator give me the value of "X" in numeric or
symbolic form.  I can also symbolically differentiate it (but this is a
poor example for that).

     I do not work for the HP division that makes these calculators.  I
just use them.
