THANK YOU!
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: Random integer
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("[Int]");
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + (int)e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + (int)e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("[Int]");
mXparser::consolePrintln("Res. 1: " + e->getExpressionString() + " = " + (int)e->calculate());
