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! 🙂

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: 10 Millions / Kilo

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("10*[M] / [k]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("10*[M] / [k]");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );

Code result

[mXparser-v.5.2.1] Res: 10*[M] / [k] = 10000.0

Case 2: List of supported metric prefixes

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
mXparser.consolePrintHelp("metric prefix");

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
mXparser::consolePrintHelp("metric prefix");

Code result
