THANK YOU FOR SUPPORTING MY WORK!
The tutorial consists of more than 200 live examples from 50 sections given separately for JAVA, C# and C++. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Case 1: Simple calculation
$$2+1$$
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("2+1");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("2+1");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());
Code result
[mXparser-v.5.2.1] Res: 2+1 = 3.0
Case 2: Changing expression string
$$2-1$$
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
