RE: smallest |cos(x)| ?
Running my programs to 100 million would take about 45 minutes ;-)
BTW corrected an error in EPS - it will now find that x = 82,425,623.5 pi.
A bit counterintuitive that the smallest COS happens for such a large argument value; I thought it would lose about 8 digits of precision after the argument reduction. In fact, how do you know there isn't a larger value that has an even smaller ε?
Cheers, Werner
