| Abstract: | Solving factorial Problem (n! ) usually was achieved by the cyclic in university computer language textbook. Writer proposed to improve the traditional factorial (n! ) Problem by Stirling approximate formula. It makes procedure simplified,speed fast, space saved. It has practical significance in the calculation and theoretical analysis. |
