说明：  下面这个程序支持加+ 减- 乘* 除/ 阶乘！ 开方？ 平方^ 取模％ 等运算 支持括号和括号内优先级 可以输入负数 不过输入负数时需要用括号括上 这个程序 一定有不少 缺点 我也没有用一些表达式 进行运算验证 这个验证的过程就交给大家把 如果各位发现输入的表达式 计算错误的话 请将表达式和结果 发到帖子上来 我会修改的
(The following procedures support the+ By- x* Except/factorial! Prescription? Square modulus ^ operator, such as support brackets and brackets priority can enter a negative number, however, when a negative input in brackets on the need for this procedure certainly has many shortcomings I have not used some expressions of the operator to verify the authentication process to If you found everyone to enter the expression you calculated wrong, then the expression and the results sent to the post up I will modify the)
