One should consider that the DM42 uses 34 digits while the HP calcs 15 (or 12?).

Sure this December is the month of accuracy discussions!
For example.

Someone should also write, though, that if the accuracy seems not that great, it depends on what one measures and how. If I am going to use planck units to measure something and my best measurement tool has the scale in millimeters, then my concerns should not be about the accuracy of the calculator, rather somewhere else.
