RPN Scientific Firmware for the Spikenzielabs Calculator Kit

[securd]

Excellent Chasfield!

As you think about this, I actually found the BigNumberMath wrapper is a handy extension of the BigNumber library (http://cerebralmeltdown.com/forum/index.php?topic=342.0)

It uses a bit too many resources for this particular calculator, but I am using BigNumberMath on another weekend project -- a 32 DECIMAL DIGIT (not bit) Arduino Due-based scientific calculator. I was inspired by this Scientific American blog relating to precision, and I though it would be cool to code an Arduino to NIST standards! (article here: http://blogs.scientificamerican.com/obse...-you-need/)

It turned out to require more resources than I had available on the Spikenzie Calculator, but seems to be working quite well on the ARM-based Due (see photo attached).

I'll send more on this later, when I get a chance to get to a useable release!

Steve.
