实现一个集合的类，并定义了集合的加法和减法-set class

说明：  若将数据表示为浮点数格式，即有exponent和mantissa两部分，用perl语言编写实现浮点格式数据加减乘除的程序。（测试时与编程语言提供的浮点数运算进行比较，包括代码文件和设计测试报告）(If the data is expressed in floating-point format, there are two parts: exponent and mantissa. Perl language is used to write the program of data addition, subtraction, multiplication and division in floating-point format. (compare floating-point arithmetic provided by programming language during test, including code file and design test report))
