C#中GDI绘图

说明：  实行了超高精度，多次进行的C++乘法计算(The C++ multiplication calculation with super high precision has been carried out many times.)

正则表达式是处理文本强有力的工具，它使用一套复杂的语法规则，能够解决文本处理领域的绝大多数问题，如验证，匹配，查找，替换等，这些问题用通常的字符串算法是很难甚至无法解决的。这里包含boost xpressive的基 本用法(boost xpressive.boost xpressive.boost xpressive.regex,match,search)
