RE: Trigonometric Functions for the HP38C/HP12C
Bob,
I would suggest using the .n registers as they're less likely to be accidentally overwritten. Only now, twenty four hours later, I read about them in the CuVee website. I found the RCL arithmetic by chance this afternoon. Better read the manual first next time. With this plenty of registers there's no need to use any financial register. Some error handling still needed as you can see in the examples, but at least the accuracy of the inverse functions is now in line with the others. Hopefully no serious issues, but please let me know if you find any. Regards, Gerson.
