Re: CORDIC Trigonometric Algorithm on an HP17BII Message #3 Posted by Eric Smith on 13 Mar 2008, 7:13 p.m., in response to message #1 by Charles
The best general reference on algorithms for elementary functions, including both "traditional" and "shiftandadd" algorithms like CORDIC, is "Elementary Functions: Algorithms and Implementation", 2nd Edition, by JeanMichel Muller.
I'm not very familiar with the capabilities of the 17BII, but implementing a decimal CORDIC generally requires two nested loops, and a table of precomputed constants with basically one table entry per digit of precision.
I suspect that series approximations are far easier to implement on the 17BII than CORDIC would be.
