## Biginteger
一个用C++写的用于学习的Biginteger类。
本人是中国江苏某三流大学计算机专业的学生，受到Java中BigInteger类的启发，自己用C++ 写了一个大整数类，目前功能还很不完善，只支持加、减、乘、比较大小而且暂不支持负数。
关于具体使用方法，请参见docs/html，这是用doxygen自动生成的帮助文档。
欢迎提出任何有益的意见和建议。
~~为了锻炼英语能力，当初写文档时都是用英文写的，现在早就懒得改了，希望见谅哈~~

使用方法举例：
#include <iostream>
#include <string>
using std::cin;
using std::cout;
int main() {
string s1,s2;
cin >> s1 >> s2;
Biginteger b1(s1),b2(s2.c_str());
try {
cout << (b1 + b2).toString() << '\\n';
cout << (b1 - b2).toString() << '\\n';
cout << (b1 * b2).toString() << '\\n';
cout << (b1 / b2).toString() << '\\n';
cout << (b1.absolute() % b2.absolute()).toString() << '\\n';
} catch(NumberFormatException &e) {
cout << e.what();
} catch(DivByZeroException &e) {
cout << e.what();
}
return 0;
}

A BigInteger class written in C + + for learning.
I am a computer major student of an ordinary university in Jiangsu, China. Inspired by the BigInteger class in Java, I have written this Biginteger class in C + +.
At present, It is not perfect and only support addition, subtraction, multiplication and comparison.Negative numbers is NOT supported temporarily.
For specific usage, please refer to docs / html, which is a help document automatically generated by Doxygen.
All useful comments and suggestions are welcome.
