讨论：想实现混合运算
本帖最后由 vfhpai9 于 2009-6-19 18:34 编辑我已实现单步运算，但无法混合运算。
如：（A+B-E）*C/D
只能算出A+B的结果。
谢谢大哥大姐了，急用啊！！！ 你怎么算的，代码贴出来看下？ #include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

可以混合运算啊
看结果：
你的代码也没有什么错误啊 搞不懂
(1+2-2) * 4 / 5 难道不是等于0.8吗?汗 谢谢啊，我再试试！！！ 问题已解决，谢谢了各位了！！！错在循环语句，用Switch循环语句即可！！！ 1# vfhpai9
