e approximation

Summary:
I ran across the approximation e ≈ 2721/1001 recently. What makes this remarkable is its accuracy relative to the size of the denominator. You can create a trivial approximation just by truncating a decimal expansion e ≈ 2718/1000 but this is only good to four significant figures, but 2721/1001 is good to seven, almost eight, […]
