摘要：A new asymptotic formula for the constant e is proposed by the continued fraction approximation. As a consequence, we deduce inequalities for the sequence (1 + 1/n)(n), and show an application of the inequalities to the proof of Keller's limit. Numerical computations and comparisons are conducted to illustrate the superiority of our new inequalities.
