Error margins

Hugh Steers showed a system, on the HP50g, for dynamic precision and error propagation at the HPCC Conference in 2007. You might want to look up the video, titled "Formlua: A New Programming Environment for HP Calculators" on Eric's Conference Video page.

Combine that with the RPL tag system, to add the sensor name, and RPL units system, and you have a pretty complete system.
