bdszh
- 偶写了个将中序表达式转化成后序表达式的程序。不过只能对单字符进行操作，现在改良了一下，能够对任意精度的数值进行运算，并且能够处理任意多的括弧（不过我并没有显式的允许输入[]或者{}，只要将它们都成（）就可以实现[]或者是{}的操作了），由于程序中间有小数点，所以在写成后序的时候，为了以便于区分输入的数据，我用下划线将它们隔离了开来。-even wrote a sequence of Chinese expressions into expressions sequence after the p
FormulaProcessor_beta1_CSharp
- 功能说明： 次组件提供的功能有二： 1、解析出数学表达式中的参数 2、计算数学表达式 此组件不但可以解析和计算数学表达式，还提供了一系列的数学基本函数，可应用于表达式中一块处理。提供的数学基本函数有：将值舍入到最接近的整数 rount(x)、向下取整函数 int(x)、向上取整 ceiling(x)、求两个数中最大数的函数 max(a,b)、求两个数中最小数的函数 min(a,b)、幂函数 pow(x,n)、求平方根的函数 sqrt(x)。 下载地址：http
