说明：  计算机组成原理 .有试验报告 程序可以完成由定点运算实现浮点运算，根据用户的输入和运算符的选择进行相应的操作，并能对用户的错误输入给出提示信息，并且在用户选择连续操作时可以无需重启程序，多次连续运算。有该程序可以方便地实现加、减、乘、除操作，并且如果想加入新的操作也十分方便（程序是分模快设计的应而可以很方便地实现功能的扩充）；同时程序的各个功能部分都给出了详细的注释，清晰易懂，方便修改、增进
(Principles of Computer Organization. There are test reporting procedures to be completed by the fixed-point calculations to achieve floating-point operations, based on user input and choice of operator for the corresponding operations, and is able to enter the user is given the wrong message, and the user selects a row operation will not be required to restart the process, many times for computing. The program can easily add, subtract, multiply, with the exception of the operation, and if you want to add a new operation is also very convenient (sub-module program is designed to be and it is easy to achieve the function of the expansion) at the same time the various procedures functional part of the Notes given a detailed, clear and easy to understand, easy to amend and enhance)
