A quick algorithms of high precision on the exponential and logarithmic functions

摘要

Through numerical analysis, and taking into account the calculating precision, computational amount and the memory space of numerical tables, these three indexes, some quick algorithms on the elementary functions are given by the method of combining computation and table search. In addition, the quick algorithms of high precision are also obtained by using some improved computational methods in this paper. Furthermore, the detailed computational process on the algorithms is demonstrated.
