一个支持大整数加减乘除运算的计算器，能显示运算时间和生成随机数，用c++编写，采用对话框窗口。-A support for large integer multiplication and division addition and subtraction calculator can show computation time and generates random numbers, written using c++, using the dialog window.

大数类，运算超长的数字,运算符都进行了重载，虽然没有说明文档但是很易懂。-The number of classes of large numbers, arithmetic of big integers.

高精度运算，实现加减乘除的计算，可以作为一个小模块使用-The high precision operation, realize the addition, subtraction, multiplication, and division calculations

采用BigInteger 类实现大素数生成，主要用于密码学RSA算法。-Using BigInteger class implements a large prime number generation, mainly for RSA cryptography algorithm.
