The Rogue HP-12c

[dm319]

Thought I would do a little video to demonstrate a few things:

1. The comma bug
2. IRR example error
3. Digit precision
4. Divide by zero issue
5. A few TVM differences
   

See here.

A couple of things I haven't done:
- I can't compare on video to an HP-12c. Maybe in retrospect I should have explained what you would have got on the HP-12c, but it is pretty similar behaviour to the HP-12c platinum but returns 10 digits rather than a maximum of 12. I also didn't show you the full 16 digit precision (just 15).

I couple of thoughts - some effort has clearly gone into making this device match an HP-12c - the way the stack lifts for example, and returning only an integer N.
