一个用C编写的计算器，可以计算带括号的计算表达式的值，仅支持整数范围内的计算（开始的时候是开发给单片机用的，由于执行效率原因，所以设计不支持浮点数计算），代码很简介，只要修改下数据类型和小部分代码就可实现完全的浮点数计算了-Calculator, written in C can calculate the value of the bracketed expression is evaluated only supports integer within the calculation (the beginning of the development to the microcontroller used, due to the implementation of efficiency reasons, so the design does not support floating-point calculation)code profiles, as long as the modified data types and a small part of the code can achieve full floating-point calculated
