I have a National Semiconductor RPN calculator that I still
occasionally use.  It's the only calculator I know that will float
(with the battery removed).  5 cubed would equal, after about two
second's thought, 124.9999999.  I think it was called the
"Scientific".  Does anyone else remember this thing?
