To get started quickly without reading the documentation, see the example code inExample.java. Here are some excerpts from it, with each bit preceded by an explanation: expris an object representing a parsed expression. Expr expr; Parse the string inargs[0]and setexprto the representation of ...
mathematical-expression 是一个针对数学公式解析的高效工具,支持 Java、Python 和 C 语言 API。它能够解析包含嵌套函数、包含函数、数列步长累加等复杂数学公式,并返回数值结果对象。此外,该框架还支持比较运算,返回布尔值结果对象。建议使用 1.3.1 版本以上,以确

BTW, in my opinion, it is impossible to put mathematical expression or formula in TextBox in Windows Forms. Some fonts or character code can show mathematical characters in it, but I suppose it is not what you want, what you want is like this. I have little knowledge about LaTex, but ...
This method carries out an initial evaluation of the expression's correctness in terms of the mathematical functions, operators, variables and constants, and properly balanced pairs of parentheses and braces used. Modular software architecture for authoring mathematical content What mathematical function can...
