What is the probability of two randomly chosen integers being coprime?
Bonus(d4): How does the result relate fo the density
of squarefree numbers?

computer approximation by Charlie)
Researching this problem shows the actual answer is 6 / pi^2. This evaluates to approximately .607927101854028, so there was more accumulated rounding error, combined with probably factor values left out at the cutoff, than I had allowed for in my claimed choice of precision representation.
