 I find I am dissatisfied with all of the HP's modes for displaying
numbers. I use standard mode, but dislike the way very small and very
large numbers are not displayed in scientific notation, so I wrote
the following:

<< DUP DUP MANT ->STR "E" + SWAP XPON ->STR + SWAP >>
save this as XPONE and assign it to the orange-shift EEX key.
(i.e., {Xpone 53.2} STOK ). Thus you will type left shift EEX to convert
the real number in level 1 into exponential notation. The result will be
placed on level 2, in a string; the number will remain on level 1.
