UCGUI计算器类文件源码下载，基于C语言环境，界面友好，大家可互相学习一下！-很好用的calculator1_UCGUI2。实现说明：把要处理的字符串转化为结构体，修正得到的结构体，如4(3+1)-->4*(3+1) , sin7-->sin(7),提高程序的应用性，把常用的数学函数用一个大写字母表示 如sin 为 H ,sqrt 为 S 把处理的字符串中的表示数字的字符化为double 型-UCGUI calculator class file download source code, based on the C language environment friendly interface, we can learn from each other about!- Good use calculator1_UCGUI2. Implementation Note: the string to be processed into the structure, the structure was modified as 4 (3+1)-> 4* (3+1), sin7-> sin (7), to improve the program application, the use of a common mathematical functions such as sin as uppercase letters H, sqrt is S　the string representation of the digital processing of the character into a double
