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: Units of length / distance
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("( 95*[cm] + 200*[m] + 1*[km] ) / [km]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("( 95*[cm] + 200*[m] + 1*[km] ) / [km]");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: ( 95*[cm] + 200*[m] + 1*[km] ) / [km] = 1.20095
Case 2: Units of time
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("( 60*[min] + 2*[h] ) / [h]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("( 60*[min] + 2*[h] ) / [h]");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
