该组件可用编写字符串和数字运算处理脚本，供运行时调用获取执行结果

1、组件调用的方式可以参考 main.cpp

2、脚本的编写可以参考 debug/my.cfg

3、可调用系统函数有

　　atof: 　　将字符串转换为浮点数

　　ceil:

　　floor:

　　abs:

　　index:

　　strcmp:

　　substr:

　　strlen:

　　trim:

　　strstr:

　　split:

　　replace:字符串替换函数

　　printf:

这些函数基本与同名c函数相同

4、可预先编写一组脚本文件，编译时为每个文件指定ID，供调用时选择-The component can be used to prepare the string and digital processing scr ipt for run-time access to results of the implementation of one call, components can call the reference main.cpp2, the preparation of the scr ipt can refer to debug/my.cfg3, may call the system function has atof : convert a string to float ceil: floor: abs: index: strcmp: substr: strlen: trim: strstr: split: replace: string replace function printf: These functions are basically the same with the same name c function 4, can be prepared in advance by one Group scr ipt file, compile-time specified for each document ID, call for selection
