Four methods of computing \(e\) and comparing the precision. (Chinese. English summary) Zbl 1228.65029
Summary: Three calculation methods are designed by Visual C++6.0. They compute the mathematical constant \(e\) respectively by limit, progression and integral. At last, the computer computes \(e\) according to the human method of computation. The result computed by limit or integral can be accurate to 7 decimal places. The result computed by progression can be accurate to 15 decimal places. The result computed according to the human method of computation can be accurate to 800 decimal places.
