Abstract:

In view of the program design requirements of the large data factorial and the super high precision solution of the natural logarithm in engineering practice, the
paper proposes the practical algorithm and the program flow diagram description of super high precision multiplication and division operation, and the time complexity degree
analysis of correlational algorithm is given also. In addition, we issue the complete C language programs of the factorial of large data and the super high precision solution of
the natural logarithm in which provides the necessary experimental data and algorithm to effectively solve the problem of super high precision programming in engineering
practice.

Key words:  , large data factorial; natural logarithm; super high precision; practical algorithm; complete C program
