基于栈结构的浮点型数据表达式求值算法

The method of calculating float data express based on stack

表达式求值是程序设计语言编译中的一个基本问题 ,任何程序设计语言都涉及到了表达式求值的功能 ,对于按常规输入即中缀表达式输入格式的表达式求值问题不但要进行整型数据的运算 ,而且更重要的是浮点型数据的运算。

Calculating expression is a basic function in programming language, because any programming language is involved with the function of calculating expression. So the calculating infix expression is important to programming language. It＇s not only involved with integer, but also more importantly, with float data.
