CORDIC in Degrees vs. Radians Message #1 Posted by Mike Fikes on 23 July 2011, 12:27 p.m.
On a Voyager (15C) in degrees mode, cos 60 = 0.5. The same is true for a Pioneer (20S).
If, instead, this is performed in radians mode, first converting 60 degrees to radians using >RAD, this results in
15C: 0.5000000002
20S: 0.499999999997
My question: How do these machines produce exactly the right answer when in degrees mode?
Is CORDIC internally performed always either degrees or radians (with the necessary conversions of input being done first)? Or is it internally performed using the mode that the calculator is set to?
