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! 🙂

Below is the code for JAVA, C# (the code for C# is almost identical) and C++. To copy the code, double-click inside the frame.
Case 1: Using built-in constants
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("pi+e");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("pi+e");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());
Code result
[mXparser-v.5.2.1] Res: pi+e = 5.859874482048838
Case 2: Estimating Moon gravitational acceleration
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 )");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());
Code result
[mXparser-v.5.2.1] Res: ( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 ) = 1.6247349715841357
Case 3: Getting list of constants
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression();
mXparser.consolePrintln(e.getHelp("constant"));
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression();
mXparser::consolePrintln(e->getHelp("constant"));
Code result
