Michael has really improved the look of his web site at http://www.rpn-calc.ch/. The home page now features a carrousel of all five calculator models.

Mindlessly spinning the calculators, I started wondering why he chose the various default display values for each model:

DM-10CC = 1.7321

Easy, 3 SQRTDM-11CC = 1.4142

Again easy, 2 SQRTDM-12CC = 1.55

The best I that I can come up with is: 111 LN LNDM-15CC = 1.6180

Pure gold, 5 SQRT 1 + 2 /DM-16CC = AA55 H

Again, no idea:

BIN 1010101 Enter Enter 1001 RLn + HEX

or

HEX 55 Enter Enter 9 RLn +

Does anyone have a better solution for the DM-12CC or DM-16CC? Maybe Michael could give us the real answers.
