【摘要】 针对5种不同的计算方法，对自然常数e的误差和收敛速度进行了比较，经过理论分析和实验计算后得到了相同的结果。结果表明：Taylor公式下的收敛速度最快，误差能够较快地达到设定值。但由于Taylor公式在MATLAB程序中存在存储和精度两方面的问题，因此引入迭代方法有效地避免了这两方面的问题，并且在一定程度上减少了计算机运行的时间。更多还原

【Abstract】 The error and convergence speed of natural constant e are compared under five different calculation methods, and the same results are obtained through theoretical analysis and experimental calculation. Among them, Taylor formula has the fastest convergence speed and the error can reach the set value quickly. Since Taylor formula has problems in storage and accuracy in MATLAB program, the iterative method is introduced, which effectively avoids these two problems and reduces the running time of computer to a certain extent.更多还原
