Here's an obscure bit of code I recently came up with.  See if you can
figure out what it does without actually simulating it:

        movwf temp
        mullw .205
        rlncf PRODH,w
        andlw 0xF0
        mullw .160
        bsf STATUS,C
        subfwb PRODH,w
        addwf temp,w

Hints:  This code does actually do something useful.  Input and output ar=
e
in W as written.  It produces valid results for inputs up to 159, althoug=
h
the range over which you'd probably use it is somewhat less than that.
