自己编写的大数库，可实现大整数的加减乘除求余，取模等多种计算，经过实验证明，所有运算都是正确的。-Write your own library of large numbers, large integer addition and subtraction, multiplication and division remainder modulo a wide variety of computing, after the experiment proved, all the operation

大二的时候写的RSA类头文件，集成了大数四则运算、幂模运算、米勒罗宾算法寻找大数等RSA加密必须的算法，详询《密码学原理与实践》-Sophomore writing the RSA class header file, integrated Tarsus four computing power modular arithmetic, Miller-Rabin algorithm must find large numbers RSA encryption algorithm, detailed

大数乘法加法，把数字转换成字符串，不论多大都可以运算啦-Large numbers multiplication, addition, converting numbers into strings, regardless of how much can be op!

大数运算，当整形数字溢出时，实现大数之间的各种数学运算-Computing large numbers, numeric overflow when shaping to achieve a variety of mathematical operations between large numbers
