mini challenge: find the smallest cosine of an integer

[EdS2]

Thanks Peter, that's very good to hear!

I would be interested to see your code. I have my 15C, 35S, and 30b ready, and all of those in principle could be programmed up for a search. (But instead I find myself playing around with Basic. And not even on a 71B.)

And thanks Albert, again: I now have a glimmering of understanding that we can't get an actual zero.
