[HP-12C] Angular coefficent from linear regression off by 1

[HP67]

I knew that Voyagers don't have it. I meant the newer ARM versions running emulation. Since they added a few other tricks I thought maybe it was supported. If it bothers you maybe you can pick up a pre ARM 12C. They're just wonderful, wonderful calculators. Mine paid for itself the day I bought it. I have no idea how available/expensive they are on the used market. One one hand I can't imagine anyone parting with one. On the other hand many people want the latest and greatest model and don't like old stuff.
